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

To use the toupper() function from the lodash library in TypeScript, you first need to install the lodash library using an npm package manager like so:

index.ts
npm install lodash
19 chars
2 lines

Then, you can import the function into your TypeScript file like this:

index.ts
import { toUpper } from 'lodash';
34 chars
2 lines

You can now use the toUpper() function in your code, passing in a string as an argument and it will return the string in uppercase.

Here is an example usage:

index.ts
const myString = 'hello world';
const upperString = toUpper(myString);
console.log(upperString); // output: HELLO WORLD
