how to use the before function from lodash in javascript

The before function in Lodash allows you to create a function that will be called at most n-1 times. Once the function has been called n-1 times, the result of the last invocation will be returned on all subsequent calls.

Here's an example usage of the before function:

index.tsx
const lodash = require('lodash');

function myFunction() {
  console.log('This function can only be called twice');
}

const myFunctionTwice = lodash.before(2, myFunction);

myFunctionTwice(); // logs 'This function can only be called twice'
myFunctionTwice(); // logs 'This function can only be called twice'

myFunctionTwice(); // does not log anything
355 chars
13 lines

In this example, myFunction will only be called twice. After that, the call to myFunctionTwice() will not execute the function and instead simply return the result of the second invocation.
