What is reference path in vscode

Question

I have downloaded Visual Studio Code for linux, and I am playing around with it. I wanted to use jQuery intellisense with it, and found a way to do it on the internet. Once I did it some sort of directive was added to my js file.

/// <reference path="typings/jquery/jquery.d.ts"/>

what does /// mean to pure javascript? it's not a comment, so how does javascript interpreter deal with this. also I am unable to find the path typings/jquery/jquery.d.ts in the local vscode folder. (although there is a typings folder there is no folder or file named jquery). So from where is this file linked to my js file?

Answer 1

Vscode will see :

/// <reference path="typings/jquery/jquery.d.ts"/>

and know it must use intellisense jQuery.

Intellisense is a vscode feature that provides instant context-aware help when writing code. It has nothing to do with your own sourcecode.

Here a really good explanation : vscode intellisense
