How To Hire JavaScript Developers Perfect for Your Project?

Without a question, JavaScript is now the most significant and widely utilized technology in IT operations. Thanks to solutions such as the React Native framework, which enables cross-platform app development for Android and iOS with the support of JavaScript, it not only powers about 95% of the world's webpages yet is now becoming increasingly widespread in mobile applications.

JavaScript is by far the most widely used programming language in the planet, with 67.8% of participants using it frequently, according to the 2019 Stack Overflow Programmer Survey. This is the seventh year in a row that JavaScript has outperformed HTML and CSS combined (63,5 percent).

JS-related products and technologies are outpacing their competitors in other fields as well. According to the same Stack Overflow study, jQuery, a JavaScript library, is perhaps the most widely used web framework (used by 48,7% of developers), with React and Angular rounding out the top three. Node.js, a platform that enables the usage of JavaScript on the back end of a webpage, took first place in the list for "Other Frameworks, Libraries, and Tools" (used mostly by 49,9% of developers).

Owing to JavaScript's enormous popularity, there are a variety of programmers on the marketplace, from seasoned professionals that have a deep understanding of the technology to recent graduates from a quick web development bootcamp. How could you be certain that the JavaScript developer you employ is in the first category and not the second? How can you be certain that you choose a team of experts that will truly propel your goods to the top?

Here seems to be our advice to finding JavaScript programmers who will actually satisfy your demands.

Hard skills every good JavaScript developer should have

Does having knowledge of JavaScript make someone a competent JavaScript programmer? Actually, no. For such a developer to truly be able to advance your project, there are more technical needs. One of most crucial hard talents to take into account while hiring JavaScript engineers are listed below.

1. Understanding of HTML and CSS

Those two languages make up the trinity of most significant web development technologies, together with JavaScript. Considering them all allows the programmer to truly build a contemporary, dynamic website since they all work well together.

2. Familiarity of essential JavaScript libraries and frameworks

There are many JavaScript frameworks and libraries available, and no programmer is familiar with them all. You could wish to employ JavaScript experts with knowledge in particularly specific frameworks based on the demands of your work. When developing front-end applications, developers frequently utilize frameworks and libraries like jQuery, React, Angular, or Vue, whereas the Node.js runtime environment, supported by frameworks including Express or Nest, is the preferred option for JavaScript-based back-end applications. React Native is a tool that may be used for developing mobile applications.

3. Knowledge of JavaScript supersets

In coding, a language that contains all the characteristics of another language and some more is referred to as a superset. Take JavaScript as an instance; TypeScript is indeed one of the supersets but is most frequently utilized in frameworks like Angular and React. Real-time code checking, one of the extra capabilities offered by TypeScript, aids in eliminating frequent software bugs. Despite the fact that there are other supersets of JavaScript, TypeScript is unquestionably the most widely used and is thus important to know about because more and more frameworks and libraries are beginning to embrace it.

4. Expertise of JavaScript testing instruments

Prior to actually making it available to the general public, every new feature of your online or mobile product needs to be evaluated. A test is conducted by developers to evaluate the functionality of their code and to look for any potential problems. One ought to be sure to recruit JavaScript web programmers that have familiarity with at least one of these tools because testing is typically conducted using distinct testing frameworks. JEST, Mocha, Jasmine, and Karma are a few well-liked JavaScript testing frameworks.

The most important soft skills of great JavaScript developers

For a JavaScript programmer, possessing all the necessary technical abilities is essential, but it's also important to have soft skills. They have a direct impact on your candidate's communication skills, and effective communication benefits the entire roster rather than just one person.
Therefore, while hiring JavaScript engineers, keep the following soft talents in mind to increase the efficiency of your project's growth and foster creativity inside your business.

1. Comprehension of the client

The creation of a user-friendly interface that is simple to use even for non-techies falls under the direct control of JavaScript developers because they frequently operate on the front-end of a website or web app. Although if you've had a UX or UI designer on staff, JavaScript programmers still have a significant impact on how their suggestions are ultimately put into practice. As a result, a key quality in the work of a JavaScript web designer is the ability to put oneself in the customer's shoes and view the product from their viewpoint.

2. Favorable to the community

Most problems and faults may be resolved quickly because to the abundance of internet information on JavaScript, provided one knows where to seek and who to ask. Because of this, it's crucial for a JavaScript developer to maintain and engage with their community both online and off.


3. Excellent self-control

The capacity to effectively handle one's time is essential given the variety of duties that a JavaScript developer must complete every day. This really is particularly crucial for early businesses and small development teams when there is a lack of dev team leadership and a lot of scheduling is handled by the individual developers themselves.

Top JavaScript developer job interview questions

How could all of the aforementioned hard and soft talents be evaluated? by conducting a suitable employment interview. Although HR is frequently used to analyze skills and experience, a tech specialist is required to evaluate hard abilities. We advise seeking the assistance of other experts if you don't consider yourself to be an expert in JavaScript. The main choices would be a software analyst, an IT project leader, or a programmer with knowledge in JavaScript.

Following are some of our preferred JavaScript programmer interview questions to give you a sense of what this type of technical interview may include. Nevertheless, please remember that almost all JavaScript engineers have a certain library or framework they specialize in, and interview questions will change accordingly.

  1. What distinguishes the terms === and ==?
  2. Event bubbling: How does it operate?
  3. What distinguishes a.call from a.apply?
  4. What is the process of prototypal inheritance?
