how to use the pad function from lodash in javascript

To use the pad function from lodash in JavaScript, first, you need to install the lodash library using npm or add it to your HTML file.

index.tsx
npm install lodash
19 chars
2 lines

or

<script src="https://cdn.jsdelivr.net/npm/lodash"></script>
60 chars
2 lines

Once you have the library installed, you can use the pad function by passing the string you want to pad, the length you want the resulting string to be, and the characters to use for padding (by default, it uses spaces).

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

const paddedString = _.pad('hello', 10, '*');

console.log(paddedString); // Output: "***hello**"
128 chars
6 lines

In the above example, the pad function is used to pad the string 'hello' with asterisks until the length of the resulting string is 10 characters.

Alternatively, you can also use the padStart and padEnd functions to achieve left and right padding, respectively.

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

const leftPaddedString = _.padStart('hello', 10, '*');
const rightPaddedString = _.padEnd('hello', 10, '*');

console.log(leftPaddedString); // Output: "*****hello"
console.log(rightPaddedString); // Output: "hello*****"
251 chars
8 lines

In the above examples, the padStart function pads the string 'hello' with asterisks to the left until the length of the resulting string is 10 characters, while the padEnd function pads it to the right.
