For Loop

A for loop is a fundamental control flow construct in programming that iterates over a sequence of elements, executing a block of code repeatedly for each item. It is widely used for tasks like processing arrays, lists, or ranges, and is supported in most programming languages with variations in syntax and functionality. For loops provide a concise way to handle repetitive operations, making code more efficient and readable.

Also known as: for, for-in loop, for-of loop, for-each loop, iteration loop

Why learn For Loop?

Developers should learn for loops because they are essential for automating repetitive tasks, such as iterating through data structures like arrays or lists to perform operations like filtering, mapping, or summing elements. They are particularly useful in scenarios like data processing, algorithm implementation, and batch operations, where manual iteration would be impractical. Mastering for loops is a foundational skill that enhances problem-solving abilities and is applicable across various domains, from web development to scientific computing.
