how to use the functions function from the underscore library in typescript

To use the functions function from the Underscore library in TypeScript, you first need to install the Underscore typings. This will allow TypeScript to recognize the functions defined by Underscore, including the functions function.

You can install the typings using the following command:

index.ts
npm install --save-dev @types/underscore
41 chars
2 lines

Once you have the typings installed, you can import Underscore and use the functions function as follows:

index.ts
import * as _ from 'underscore';

const myFunctions = _.functions(myObject);
77 chars
4 lines

The functions function takes an object and returns an array of the names of its own enumerable properties that have function values.

In the example above, we use the import statement to import all the functions provided by the Underscore library. We then use the functions function to get the names of the functions in the myObject object.

Note that you need to have Underscore available in your project for this to work. You can install it using the following command:

index.ts
npm install --save-dev underscore
34 chars
2 lines

Once you have it installed, you can import it in your TypeScript files and use the functions function as described above.
