How does lodash.after work?

lodash.after is a higher-order function that takes two parameters: a number indicating how many times the generated function must be called before the wrapped function is invoked, and a function to be called once the condition is met. The returned function keeps track of how many times it has been called by incrementing an internal counter, and it executes the given function only when the counter reaches the specified value. After the wrapped function has been called, subsequent calls to the generated function return the result of the wrapped function.

const _ = require("lodash");

function logMessage() {
  console.log("Message logged after 3 calls");
}

const logMessageAfterThreeCalls = _.after(3, logMessage);

logMessageAfterThreeCalls(); // no output
logMessageAfterThreeCalls(); // no output
logMessageAfterThreeCalls(); // "Message logged after 3 calls" is output to the console

In this example, logMessageAfterThreeCalls is a function that executes logMessage only after it has been called three times. The first two calls to logMessageAfterThreeCalls do not result in any output, but the third call logs the message "Message logged after 3 calls" to the console.
