A lot of different frameworks and libraries have been developed based on JavaScript which has managed to streamline and speed up JavaScript app development.

Most of the popular tools are capable of event handling, code-reduction, and also data rendering. When looking to hire JavaScript developers, look out for professional experience using toolkits like:

• Aurelia
• Vue.js
• React
• Backbone.js

Another essential skill you should look for when hiring JavaScript developers is knowledge of version control. The professional you hire will be working with a team of developers (front and back-end).

Expert JavaScript developers must also be familiar with JavaScript's security best practices to help prevent common web vulnerabilities during software development. These threats range from cross-site scripting (XSS) and injection attacks to cross-site request forgery (CSRF). Hence, when you hire a JavaScript developer, check if they are proficient in techniques such as output encoding, input validation, and proper data handling for maximum security.

Creating user-friendly, business-ready applications is imperative to success. For this, a JavaScript developer must possess a solid understanding of testing frameworks like Jasmine, Mocha, and Jest, as well as debugging techniques. Your chosen developer must be able to write unit tests, perform integration testing, and efficiently debug JavaScript code through Node.js debugging features. Additionally, a skilled JavaScript developer must be able to optimize the JavaScript code's performance, through algorithm optimizations, network request minimization, and rendering performance improvements.

If you're entrusted to hire JavaScript developers, it is wiser to recruit using a hiring funnel. It will help to ascertain experience and skill level and also identify professionals best suited for your company.
