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

To use the add function from the lodash library in TypeScript, you need to first install the lodash library:

npm install --save lodash
26 chars
2 lines

Then you can import the add function and use it in your code:

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

const result = add(2, 3);
console.log(result); // 5
83 chars
5 lines

Note that if you are using TypeScript version 3.8+, you can also use the new "import type" syntax to just import the types of the add function without importing the actual implementation:

index.ts
import type { Add } from 'lodash';

const result: Add = add(2, 3);
console.log(result); // 5
93 chars
5 lines

This can help reduce the size of your compiled JavaScript code, as the implementation of the add function will not be included in the output.
