Comparing Loop Structures in JavaScript

What are the main types of loop structures in JavaScript?

The main types of loop structures in JavaScript are for, while, and do...while loops. Each has its own use cases.

Can you explain the differences between a for loop and a while loop?

Sure! A for loop is typically used when the number of iterations is known, while a while loop is used when the number of iterations is not predetermined.

When should I use a do...while loop?

A do...while loop is useful when you want to ensure that the loop body is executed at least once, regardless of the condition.

Which loop structure is the most efficient?

Efficiency can depend on the context, but generally, for loops are considered more efficient for iterating over arrays due to their predictable structure.
