Vscode is the favourite text editor for most developers. It's extensions make it life easier for developers. But a thing i experienced while working with jsp, servlets, springmvc ,etc , that developers don't prefer working with vscode. The main reason being there was no extension for jstl snippets which can work flawlessly when language mode is HTML, so that one can use emmet features and jstl snippets at the same time. The extensions available will generate some limited snippets that too when language mode is JSP, so now you don't have access to the emmet features.
So to overcome these problems I have created a vscode extension which will provide all above features at the same time. You can check the extension following the below link: https://marketplace.visualstudio.com/items?itemName=DebrajBhal.jstl-snippets-by-deb
