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

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

index.ts
npm install lodash

2 lines

Once you have installed the library, you can import the function and use it in your TypeScript code:

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

const logHello = () => {
  console.log('Hello!');
};

const logHelloAfterThreeCalls = _.after(3, logHello);

logHelloAfterThreeCalls(); // does not log anything
logHelloAfterThreeCalls(); // does not log anything
logHelloAfterThreeCalls(); // logs "Hello!"

12 lines

In this example, logHello is a function that logs "Hello!" to the console. We then pass logHello and the number 3 to _.after to create a new function, logHelloAfterThreeCalls, that will only execute logHello after it has been called three times.

We then call logHelloAfterThreeCalls three times; the first two times, the function does not log anything because it has not yet been called three times. The third time we call the function, logHello is executed and "Hello!" is logged to the console.
