The JavaScript while and do…while loops repeatedly execute a block of code as long as a specified condition is true. In this tutorial, you will learn about the JavaScript while and do…while loops with examples.
While Loop TheJavaScript while loopconsists of a condition and the statement block. while (condition) {...statements...} The condition is evaluated. If the condition is true the statements are evaluated. If the statement is false we exit from the while loop. ...

Let's now consider a couple of examples of using these operators: 10 < 50 true 10 < 10 false 10 < 9 false 10 > 10 false 10 > 9 true 10 >= 10 true 10 <= 10 true 10 === 10 true 10 === 9 false We'll discover more relational operators in JavaScript in one of the upcoming...
Python while loop: Loops are used to repeatedly execute block of program statements. The basic loop structure in Python is while loop. See the syntax and various examples.
Another common and extended use case of while loops in Python is to create event loops, which are infinite loops that wait for certain actions known as events. Once an event happens, the loop dispatches it to the appropriate event handler. Some classic examples of fields where you’ll find ...
Example: For loop in C Compiler // Program to print numbers from 1 to 10 #include <stdio.h> int main() { int i; for (i = 0; i < 10; i++) { printf("%d\n", i+1); } return 0; } Run Code >> The above code prints the numbers from 1 to 10 using a for loop in...
