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

To use the throttle function from the lodash library in TypeScript, you need to first install the Lodash library by running the command npm install lodash in your TypeScript project. After installing the library, you can import the throttle function and use it in your code. Here is an example:

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

function expensiveFunction() {
  // Perform expensive operations here
}

const throttledFunction = throttle(expensiveFunction, 1000);

// Call the throttled function
throttledFunction();

In the above example, we are importing the throttle function from the lodash library. We declare an expensive function and then create a throttled function using the throttle function with a delay of 1 second (1000 milliseconds). Finally, we call the throttled function.

The throttle function returns a new function that can be called repeatedly, but only once per specified delay. This can be useful for limiting the rate at which certain events are fired, such as resize and scroll events in a web application.
