ES6 JavaScript Snippets for Visual Studio Code

A JS snippets pack largely inspired by other snippet extensions on VSCode (Charalampos Karypidis, Mahmoud Ali, Dsznajder) but with a few of my own twists and added snippets !! :)

Supported languages (file extensions)

• JavaScript (.js)
• TypeScript (.ts)
• JavaScript React (.jsx)
• TypeScript React (.tsx)
• Html (.html)
• Vue (.vue) (Vetur extension required)

Hints

1. control/command + space loads the snippet suggestions if they aren't shown right away.
2. ${1} is where the snippet starts. $0 is where the snippet ends.
3. Press tab to move onto the next part of a snippet.
