Master the art of repetition! Learn for loops, while loops, and how to iterate through arrays. Loops are essential for processing data and avoiding repetitive code.
Instead of writing the same code many times, use a for loop to repeat it!
One of the most common uses of loops is going through every item in an array!
Loops are perfect for calculations like adding up numbers or counting things!
While loops repeat as long as a condition stays true. Great when you don't know exactly how many times to loop!
You can often accomplish the same thing with either for or while loops. See the difference!
Sometimes you want to stop a loop before it naturally ends. Use break!
Continue lets you skip the rest of the current loop iteration and jump to the next one!
You can put loops inside other loops! This creates patterns and processes 2D data.
Modern JavaScript has a cleaner way to loop through arrays called for-of!
