What are the differences between while loops and for loops?

What are the differences between while loops and for loops?

While loops continue until a condition is false, whereas for loops iterate a specific number of times.

Can you give me an example of each?

Sure! A while loop example: while (i < 5) { console.log(i); i++; }. A for loop example: for (let i = 0; i < 5; i++) { console.log(i); }.

When should I use one over the other?

Use a for loop when you know the number of iterations in advance. Use a while loop for indefinite iterations.

Are there performance differences between them?

Generally, performance is similar, but for loops can be slightly faster in some cases due to optimizations.
