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

To use the apply function from the Underscore library in TypeScript, you first need to install the library. You can do this by using npm, the package manager for Node.js:

npm install underscore

2 lines

Once Underscore is installed, you can import it in your TypeScript code using the following code:

index.ts
import * as _ from 'underscore';
33 chars
2 lines

Then, you can use the apply function by passing it an object to call the function on, the function to call, and the arguments to pass to the function. Here's an example:

index.ts
const numbers = [1, 2, 3, 4, 5];
const max = _.apply(Math, Math.max, numbers);
console.log(max); // Output: 5
110 chars
4 lines

This code calls the Math.max function on the array of numbers using the apply function from Underscore. The first argument is the object to call the function on (in this case, the global Math object). The second argument is the function to call (Math.max), and the third argument is the array of arguments to pass to the function.

Note: the apply function in Underscore is similar to the apply method in JavaScript.
