This JavaScript tutorial explains how to use the for loop with syntax and examples. In JavaScript, the for loop is a basic control statement that allows you to execute code repeatedly for a fixed number of times.
The for loop is ideal when you know how many times you want to execute a block of code. It provides more control than while loops for counting iterations. Basic for loopThe following example demonstrates the basic usage of the for loop in JavaScript. main.js ...
"array value: 1" "array value: 2" "array value: 3" "array value: a" "a is string at index: 3,loop stoped using return" We’ve achieved the same result as the first example by using the return keyword. We have placed that for loop code in the function’s body and used the ...

don’t want to put a condition or a way to get out of the loop, you would be building an infinite loop. But if this is not your intention then you will have to put a condition and an expression that changes the value of the variable, as we have done in the previous code snippet...
Apart from this, it's also not necessary to declare the loop variable in the loop's header — it could be declared before as well. For example, the same code above could be expressed as follows: JavaScript var i; for (i = 0; i <= 4; i++) { console.log(i); } Here, i is...
