21-for-loops

Lesson 21: for loops

for, for…of, for…in.

What you'll learn

• classic for (let i = 0; i < n; i++) for index control
• for…of iterates array/iterable VALUES
• for…in iterates object KEYS (avoid on arrays)
• prefer for…of / array methods over index loops when you don't need the index

Example
