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

To use the noop function from the lodash library in TypeScript, first ensure that you have installed the @types/lodash package in your project. This allows TypeScript to understand the types returned by the lodash methods.

Then, you can import the noop function from the lodash library like this:

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

Finally, you can use the noop function in your TypeScript code as follows:

index.ts
function myFunction(param1: string, param2: number): void {
  // do something with the parameters
}

// Use the noop function as a default parameter value
function myOtherFunction(callback: () => void = noop): void {
  // do something with the callback function, or call it if it exists
  callback();
}

In the above example, we use the noop function as a default parameter value for the callback argument in the myOtherFunction function. If no callback is provided, the noop function will be used instead, which does nothing and returns undefined. This is a useful way to avoid checking for a null or undefined value before calling a callback function, since the noop function ensures that a valid function reference is always provided.
