What are the loops in JavaScript?

Loops are used in JavaScript to perform repeated tasks based on a condition. Conditions typically return true or false when analysed. A loop will continue running until the defined condition returns false . You can type js for , js while or js do while to get more info on any of these.

Loops are control structures used to repeat a given section of code a certain number of times or until a particular condition is met. Visual Basic has three main types of loops:

1. for.. next loops,
2. do loops
3. while loops.

for (let i = 0; i < cars.length; i++) { text += cars[i] + "
"; }

while (i < 10) { text += "The number is " + i; i++; }

example(3):

do { text += "The number is " + i; i++; } while (i < 10);
