Here are 9 great extensions that will dramatically improve your JavaScript development:

1. Visual Studio Intellicode

IntelliCode saves you time by putting what you’re most likely to use at the top of your completion list. IntelliCode recommendations are based on thousands of open source projects on GitHub each with over 100 stars. When combined with the context of your code, the completion list is tailored to promote common practices.

IntelliCode will assist you across different JavaScript libraries, whether you’re writing client-side code with frameworks like React, Angular, or Vue or doing server-side development with Node.js.
