New York, NY


Dear Hiring Manager,

With a genuine appreciation for innovative web development, I've followed your company's outstanding contributions to digital spaces closely. The creativity infused into your projects is akin to the standards I strive for in my professional pursuits.

While at ABC Corp, my initiative to revamp a key application interface streamlined user interactions, directly causing a 20% surge in user engagement. This challenge required an intricate balance of aesthetic design and technical performance optimisation. At the peak of this project, leading my team with a targeted strategy resulted in enhancing page load speed by a notable 15%, simultaneously setting a precedent for robust UI performance.

I am eager to bring my track record of successful UI projects and proven coding expertise to your esteemed team. The opportunity to discuss how my experience aligns with your company’s goals excites me. I look forward to potentially exploring this further in an interview.

Best regards,

Charlotte May

What makes this cover letter good:

  • Emphasize relevant achievements: The cover letter showcases how the candidate's initiative to redesign an application interface resulted in a substantial increase in user engagement (20%). This demonstrates a direct impact on business metrics, a desirable outcome for a potential employer.
  • Highlight technical successes: Mentioning the enhancement of a page load speed by 15% suggests the candidate not only focuses on aesthetics but also on technical efficiency, critical for a Frontend Developer role where optimization is key.
  • Showcase leadership and strategy: By speaking about leading a team with a targeted strategy, the candidate demonstrates capabilities beyond individual contributions, conveying that they have the experience and the soft skills needed to manage projects and lead a team effectively.

What are the basics of the design or format of your javascript developer cover letter?

To start, here's a reminder for you: the Applicant Tracker System (or software that is used to assess candidate profiles), won't be reading your javascript developer cover letter.

Recruiters enjoy reading javascript developer cover letters with a standardized format that uses:

  • the same font as the resume (e.g. modern ones like Raleway or Volkhov are prefered over the clichéd Times New Roman or Arial);
  • single spacing to keep the content concise and organized (this is all ready for you in our cover letter templates);
  • a one-inch margin to wrap around the text, like in our cover letter builder;
  • PDF as a file format, as it allows your design (and visual element) to stay the same.

Finally, we can't go on without mentioning the key sections of your javascript developer cover letter.

In the top one-third, make sure to include a header (with your contact information, name, role, and date), a salutation, and an introduction.

Next, follows the heart and soul of your javascript developer cover letter or its body.

End your javascript developer cover letter with a closing paragraph and, if you wish, a signature.

  • Professional Experience and Technical Skills: Highlight your relevant programming experience, particularly with JavaScript frameworks and libraries, providing examples of projects and your role in them to showcase your direct experience and qualifications.
  • Closing and Call to Action: Conclude by expressing your eagerness to discuss how you can contribute to the company's projects, and politely invite them to contact you, showing proactiveness and your communication skills, essential for collaborative development environments.

Key qualities recruiters search for in a candidate’s cover letter

  • Proficiency with core web technologies (JavaScript, HTML, and CSS): Essential for building and manipulating web interfaces.
  • Experience with popular JavaScript frameworks and libraries (React, Angular, Vue.js, Node.js): Demonstrates ability to work with modern development tools and create rich, interactive web applications.
  • Understanding of asynchronous request handling, partial page updates, and AJAX: Key to creating seamless user experiences with dynamic content updates.
  • Familiarity with front-end build tools (Webpack, Gulp, Grunt) and version control systems (Git): Indicates an organized workflow and the ability to manage code effectively across development environments.
  • Knowledge of cross-browser compatibility issues and ways to work around them: Crucial for ensuring consistent user experiences across various browsers and devices.
  • Problem-solving skills and attention to detail: Important for debugging code, optimizing performance, and developing high-quality, maintainable software.

How to start your javascript developer cover letter: with a greeting, of course

Have you ever considered just how powerful a personalized salutation can be?

We sure have news for you! Your javascript developer cover letter should start with the right salutation to recruiters, nurturing a sense of respect and individuality.

Greet recruiters by using their first name (e.g. "Dear Tom" or "Dear Patricia") if you've previously established contact with them.

Otherwise, opt out for the less familiar, "Dear Ms. Peaches" or "Dear Ms Kelsey", if you've found the recruiter's name on LinkedIn or a corporate website.

"To whom it may concern" is never a good option, as it creates a sense that you've been sending out your javascript developer cover letter to anyone. Instead, use "Dear HR team" or "Dear (company name) recruiter" for a feeling of exclusivity.

List of salutations you can use

  • Dear Hiring Manager,
  • Dear [Company Name] Team,
  • Dear [Department Name] Manager,
  • Dear Mr./Ms. [Last Name],
  • Good Day [Last Name] Team,
  • Dear Selection Committee,

The javascript developer cover letter intro: aligning your interest with the company culture

You only have one chance at making a memorable first impression on recruiters with your javascript developer cover letter.

Structure your introduction to be precise and to include no more than two sentences.

Here are some ideas on how to write a job-winning javascript developer cover letter introduction:

  • get creative - show off your personality from the get-go (if this aligns with the company culture);
  • focus on your motivation - be specific when you say what gets you excited about this opportunity.
Intro Paragraph
Immersed in the transformative potential of JavaScript, I am keen to contribute to [Company Name]'s mission to harness cutting-edge technology for impactful solutions. Your commitment to innovation and responsible tech resonates deeply with my professional ethos and the craftsmanship I bring to every line of code.

The middle or body of your javascript developer cover letter body: a great instrument to tell a story

Now that you've set the right tone with the greeting and introduction of your javascript developer cover letter, it's time to get down to business.

Hear us out, the body of your javascript developer cover letter is the best storytelling instrument you have, in your job-hunting arsenal.

Writing the next three to six paragraphs, take the time to reassess the advert to discover job-crucial requirements.

Next, choose one accomplishment that covers those key skills and talents.

Use precisely that achievement to tell an exciting story of how you match the ideal candidate profile.

In the undertones of your story or javascript developer cover letter body, hint at the difference you'd make and sell your application as the perfect one for the job.

Body Paragraph
During a critical sprint, my implementation of a custom, lightweight JSON diff algorithm accelerated the real-time sync feature's efficiency by 300%. This innovation significantly reduced the server load and was key in enhancing user experience for a SaaS platform with over 10,000 daily active users.

Ending your javascript developer cover letter to avoid "Sincerely yours"

Yes, this sort of closing statement may work best before your signature.

But you want to give recruiters something more with your javascript developer cover letter ending.

Some professionals choose to go down the path of promises. In a single sentence, they map out what they'd bring about to the role (whether that's a particular technical skill set or personal traits).

Others, decide to be more concrete by thanking recruiters for their time and prompting for their next interview.

Whatever path you choose, remember to always be polite and respectful of the opportunity you've had. Good manners go a long way.

Closing Paragraph
Eager to bring my expertise to your team, I welcome the opportunity for an interview to discuss how I can contribute to your project’s success.

Keep this in mind when writing your zero experience javascript developer cover letter

Even though you may not have any professional experience, your javascript developer cover letter should focus on your value.

As a candidate for the particular role, what sort of skills do you bring about? Perhaps you're an apt leader and communicator, or have the ability to analyze situations from different perspectives.

Select one key achievement from your life, outside work, and narrate a story that sells your abilities in the best light.

If you really can't think of any relevant success, you could also paint the picture of how you see your professional future developing in the next five years, as part of the company.

Key takeaways

Winning recruiters over shouldn't be difficult if you use your javascript developer cover letter to tell a story that:

  • Is personalized by greeting your readers and focusing on key job skills greets;
  • Isn't spread all over the place, but instead focuses on one key achievement and selling your value as a professional;
  • Introduces your enthusiasm for the role, passion for the job, or creativity in communication;
  • Is also visually appealing - meeting the best HR practices;
  • Ends with a nod to the future and how you envision your growth, as part of the company.
