#11 JavaScript While Loop | JavaScript for Beginners Course

In programming, loops are used to repeat a block of code. In this video, we will learn about the while loop.

The while loop in Python is used to iterate over a block of code as long as the test expression (condition) is true. We generally use this loop when we don't know the number of times to iterate beforehand.

Watch the full video to have a clear understanding of the working of JavaScript While Loop.

(Option 4 - All of above) is the correct answer .

In option 1 " while (true) {...} " -> The loop will run for infinite times because the loop has no counter so its always true.
In option 2 "let i =3; while ( i < 4) {....} -> The loop has counter but their is no counter updater so i = 3 will always be i < 4 and so it will create an infinite loop.
In option 3 "let i =3; do { ....} while ( i < 4)" -> Its the same as option 2 only difference is it done using and the "do while" loop.

3. let i = 3;

...} while(i < 4)

All of the above will cause an infinite loop because we don’t know if the values were incremented in the body of the loop.
