while loop in javascript

A while loop is used to repeat a block of code as long as the specified condition is true. In JavaScript, the syntax for a while loop is as follows:

index.tsx
while (condition) {
  // code block to be executed
}

4 lines

The condition is checked before each iteration of the loop. If it is true, the code block inside the loop will be executed. The loop will continue to iterate as long as the condition remains true.

Here's an example of a while loop that prints the numbers 0 to 4 to the console:

index.tsx
let i = 0;
while (i < 5) {
  console.log(i);
  i++;
}

In this example, the condition is i < 5, which means the loop will continue to iterate as long as i is less than 5. The i variable is incremented by 1 in each iteration using the i++ shorthand for i = i + 1. The output of this code will be:

index.tsx
0
1
2
3
4
