WHILE LOOPS
While loops are a control flow structure in programming that allow you to repeat a block of code while a certain condition is true.
The while loop is used when the number of iterations is not known in advance, and it continues to execute as long as the specified condition is true.
1let i = 0;
2while (i < 5) {
3 console.log(i);
4 i++;
5}
6How this works?
This loop will print the numbers 1 through 5 to the console.
It's important to include a way to update the condition within the loop, otherwise it will become an infinite loop and will run forever. In the example above, the i++ statement increments the value of i by 1 at the end of each iteration, which eventually causes the condition to be false and the loop to exit.
Tip : While loops can be a useful tool in JavaScript, but it's important to use them with caution. If the condition is never met, the loop will become an infinite loop and will run forever. Make sure to include a way to update the condition and eventually exit the loop to avoid this issue.
