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

To use the _.upperCase() function from the Lodash library in TypeScript, first make sure that you have installed the Lodash library and its types.

You can do this by running the following command in your terminal:

index.ts
npm install --save lodash @types/lodash
40 chars
2 lines

Then, you can import the upperCase function from Lodash and use it in your TypeScript code.

index.ts
import { upperCase } from 'lodash';

const str: string = 'Hello World';
const upperStr: string = upperCase(str);

console.log(upperStr); // Output: HELLO WORLD
160 chars
7 lines

The upperCase function takes a string as input and returns the string with all characters converted to uppercase letters.
