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

The apply function in the Underscore library allows you to apply a function to each element of an array.

Here's an example usage of apply:

index.tsx
const _ = require('underscore');

const numbers = [1, 2, 3, 4, 5];

const result = _.apply(Math.max, null, numbers);

console.log(result); // Output: 5
152 chars
8 lines

In this example, we are using the apply function to find the maximum number in an array of numbers. The first argument to the apply function is the function to apply, which in this case is Math.max. The second argument is the context in which to apply the function, which we set to null. The third argument is the array of values to pass to the function, which is numbers.

The apply function is a powerful tool that can be used to apply any function to any array of values. It is a key part of functional programming in JavaScript, allowing you to write expressive, declarative code that is easy to read and maintain.
