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

To use the throttle function from the underscore library in TypeScript, you first need to install the underscore library as a dependency. You can install it using npm by running the following command in your project directory:

index.ts
npm install underscore

Once the underscore library is installed, you can import the throttle function and use it in your TypeScript code. Here's an example:

index.ts
import * as _ from 'underscore';

function myFunction() {
  console.log('Function called');
}

const throttledFunction = _.throttle(myFunction, 1000);

// Call the throttledFunction 3 times with a 500ms interval between each call
setInterval(throttledFunction, 500);
setInterval(throttledFunction, 500);
setInterval(throttledFunction, 500);

13 lines

In this example, we import the entire underscore library using the * as _ syntax. We define a function myFunction that we want to throttle. We then create a new function throttledFunction using _.throttle, passing in myFunction as the first argument and the desired throttle interval (in milliseconds) as the second argument. Finally, we call throttledFunction multiple times with a 500ms interval between each call.

Note that the throttle function returns a new function that you can call instead of the original function. The new function will only be called once per throttle interval, regardless of how many times it is called. If you need even more control over the behavior of your throttled function, you can use the debounce function from underscore instead.
