WHILE LOOP: ✓ While loop is a control flow statement that is used to execute a code repeatedly when the specified condition is true. ✓ If the condition is false then the code is stop and breaks the loop. ✓ If the condition never becomes false then the code will runs repeatedly.This is called infinite loop. SOME EXAMPLE PROGRAM FOR WHILE LOOP: 1.Print 1 2 3? let i = 1; while (i <= 3) { console.log(i); i++; } ✓First take the initial value i = 1; ✓Then give the condition , our final value is 3, so take the value less than 3. ✓ Print the value of i. ✓Then increment the value of i. WORKING: First the initial value starts 1 2.Then check the condition it's executes when the condition evaluates true. 3.Then prints the initial value 1 i is 1 (1 <= 3 is true). Prints 1, then i becomes 2. 4.i is 2 (2 <= 3 is true). Prints 2, then i becomes 3. 5.i is 3 (3 <= 3 is true). Prints 3, then i becomes 4. 6.Then checks i is 4. But 4 <= 3 is false,so the loop will stop. 2.Print 3 2 1? let i
