Anonymous Functions

01 How It Works

Think of a nameless utility tool built specifically for a single quick job task.

Used primarily as values or inline callbacks where permanent naming is unnecessary.

setTimeout(function() {
  console.log("Executed later");
}, 1000);

1. 1. Omit the name identifier after the function keyword.

2. 2. Assign to a variable or pass directly as a callback argument.

3. 3. Invoke via reference or context trigger.

02 Practical Example

Here is how you might see this concept applied in real-world code:

let numbers = [1, 2, 3].map(function(n) {
  return n * 2;
});
