How does underscore.string.pad work?

underscore.string.pad is a string utility function that takes a string and adds padding characters at the start and/or end of the string to make it a specific length. It takes three arguments: string: The input string that needs to be padded. length: The desired length of the string. padString: The character(s) to use for padding. The function determines how many padding characters are needed and where to add them based on the length of the input string and the desired length. If the desired length is shorter than the input string, no padding is added.

const _ = require("underscore.string");

const paddedString = _.pad("hello", 10, "-");
console.log(paddedString); // Output: "--hello---"

In this example, we first import the underscore.string library, which provides us access to _.pad. We then call _.pad with three arguments: the string to pad ('hello'), the total length of the padded string (10), and the character to use for padding ('-'). The resulting paddedString variable contains the padded string, and we log it to the console using console.log. The output in this case is --hello---, because we specified that the padding character should be a hyphen ('-').
