13 Things You Should Consider When Interviewing a JavaScript Developer

Nowadays more and more companies focus on front-end development, putting the UI/UX component of their software products in the first place. JavaScript is considered to be the language of future. Therefore, the job websites are now full of vacancies that invite JavaScript developers to join the front-end development teams, and sometimes the demand is even higher than supply.

If you’re looking for a professional, experienced and highly-qualified JavaScript developer, then you have come to the right place. In this article, we are going to highlight some key technical skills that are a must for JavaScript programmers.

Must-Have Technical Skills of a JavaScript Programmer

  1. Deep understanding of JavaScript itself, for example, understanding of prototypal inheritance, functional programming vs. object-oriented programming, and some variations of a module pattern.
  2. Good understanding of AJAX – a set of client-side web development methods that is used to create asynchronous web applications.
  3. Basic understanding of web markup, including HTML5 and CSS3.
  4.     Knowledge of advanced JavaScript libraries and frameworks, such as AngularJS, KnockoutJS, BackboneJS, ReactJS, etc. – depending on the stack of your project.
  5. Understanding of Document Object Model (DOM). Document Object Model is a programming interface specification, which is developed by the World Wide Web Consortium. JavaScript developers use DOM to create and modify XML documents and HTML pages as fully-fledged program objects.
  6. Understanding of one-way data flow and two-way data binding as well as differences between them.
  7. Understanding of asynchronous programming and its importance for JavaScript.
  8.     Ability to name the pros and cons of monolithic vs. microservice architectures.
  9. Experience with cross-browser compatibility issues and how to deal with such issues.
  10.  Familiarity with front-end build tools, such as Gulp or Grunt.
  11.  Experience with front-end package management tools, such as npm and Bower.
  12.  Knowledge of the Domain Driven Design and Test Driven Development principles.

If your candidate can answer questions related to this skillset, it means that they have enough experience to join your front-end development team and become a valuable resource for your project. We wish you good luck and hope that you will make the right choice!
