Understanding loops

There are many ways to create loops in JavaScript, but the most common are the for and while statements and variations of them that are specific to arrays and objects. Also, functions in JavaScript can be used to create loops when using recursion. In this section, we will look at only the for, while, and do...while statements.

while

The while statement creates a loop that executes a block of code as long as the condition is true. The condition is evaluated before executing the block of code:

let i = 1;
while (i <= 10) {
    console.log(i);
    i++;
};

do...while

The do...while statement creates a loop that executes a block of code at least once even if the condition is not met, and then repeats the loop as long as the condition is true. The condition is evaluated after executing the block of code:

let i = 0;
do {
    console.log(`i value: ${i}`);
    i++;
} while...
