Closure Counter

• Define the function counter that returns a function that returns an increasing value.
• The first value should be 1.
• You're going to have to use closures.

Example:

• const newCounter = counter();
• newCounter() // 1
• newCounter() // 2

Closure:

A closure is the combination of a function bundled together (enclosed) with references to its surrounding state (the lexical environment). In other words, a closure gives you access to an outer function’s scope from an inner function. In JavaScript, closures are created every time a function is created, at function creation time.
