Consuming

You can use lodash in TypeScript code without much difficulty. This applies to both module and global code. For example, once you run npm install for the type declarations, you can import and use it 

import * as _ from "lodash";
_.padStart("Hello TypeScript!", 20, " ");

Or, if you are not using modules, you can use the global variable _. 

_.padStart("Hello TypeScript!", 20, " ");
