TIL: How to add moment.js intellisense to VSCode

npm install --save-dev @types/moment

Run that command at the root of your workspace folder, and that’s it. All the moment classes and methods are available in intellisense. To confirm, open the package.json in the workspace root folder. It should have a line like this:

"devDependencies": {
    "@types/moment": "^2.13.0",

Simples :)
