Loops in JavaScript
Explore the fundamentals of loops in JavaScript, including how loop conditions control repeated execution of code blocks. Learn the syntax and application of various loop types such as while, do-while, for, for-in, for-of, and forEach. Understand how to implement loops that efficiently iterate until a condition fails, and recognize the importance of avoiding infinite loops in your programs.

Loops need a dependent condition as it continues to iterate the same set of instructions until the condition fails.
The illustration gives an overview of the look of a program flow for a loop. Let’s list the properties.
Loops features
A program loop has the following properties:
- A condition which can be
trueorfalse - A program block that is executed while the condition is
true
With these features in mind, let’s map them to the corresponding JavaScript syntax.
