how to use the ceil function from the lodash library in typescript

To use the ceil function from the lodash library in TypeScript, you should first install both lodash and the corresponding type declarations using npm:

index.ts
npm install lodash @types/lodash

Once you have lodash and its types installed, you can import the ceil function from the lodash math module and use it in your TypeScript code like so:

index.ts
import { ceil } from 'lodash/math';

const result1 = ceil(4.01); // returns 5
const result2 = ceil(6.43, 1); // returns 6.5
const result3 = ceil(8.99, 1); // returns 9

console.log(result1, result2, result3);

In this example, ceil is used to round up numbers to their nearest integer, or to a specified number of decimal places.

The first argument is the number you want to round up, and the optional second argument specifies the number of decimal places to round up to.

With this setup, you can take advantage of the convenient functions in lodash to write more expressive and concise Typescript.
