There are several businesses out there who are creating web applications, so how do you distinguish yourself from the competition? The key is to develop high-performing web applications and for that you need to hire JavaScript developers with top-notch skills and expertise.

Here are a few essential skills that you must look for when you hire JavaScript professionals:

1-- Proficient in JavaScript fundamentals
A solid grasp of the foundations of the JavaScript language is at the basis of any outstanding JavaScript developer. This entails having a firm grasp of ideas like asynchronous programming, event bubbling, hoisting, prototype inheritance, and closures. Given that these principles serve as the basis for more complex development jobs, it is imperative that you evaluate a JavaScript developer's proficiency with them before hiring them.

2-- Understanding of version control systems
A competent JavaScript developer should know how to use Git and other version control systems. Maintaining a history of code updates, working with other developers, and tracking changes all depend on version control. This ability guarantees your development team to operate effectively while lowering deployment and code management concerns.

3-- Experience in modern JavaScript frameworks and libraries
Being proficient with contemporary JavaScript frameworks and libraries is crucial in the fast-paced development world of today. Popular frameworks like React, Angular, or Vue.js, which facilitate quicker development and produce scalable, maintainable codebases, should be familiar to developers. Businesses may make sure their apps are designed with the newest technology, which helps to improve performance and user experience, by hiring developers knowledgeable in these frameworks.

4-- Problem-solving and debugging
Debugging and fixing difficult problems that come up during development are common tasks in JavaScript development. It is important for developers to know how to use debugging tools like Chrome DevTools and to approach problem-solving methodically. It takes strong problem-solving abilities to guarantee that your projects are completed on schedule and to the highest possible standards.

5-- Ability to write clean and efficient code
The ability to write clear, understandable, and effective code is a sign of a proficient JavaScript developer. This entails following coding guidelines, making sure that documentation is accurate, and performance-enhancing code. Following these guidelines not only makes code easier to maintain, but it also lowers the long-term risk of problems and technical debt.
