do-while Loop
After for loop and while loop in JavaScript , another most common loop used is do-while loop in JavaScript. The do-while loop in JavaScript is a control flow statement that allows you to execute a block of code repeatedly as long as a specified condition becomes true. Unlike other loops, the do-while loop guarantees the execution of a block of code at least once before checking the condition. It prints the statement at least once and then checks the condition.
The syntax of do-while loop in JavaScript is:
do{
//code
} while(condition);
Here's how the do-while loop works:
- The code block inside the do statement is executed first, without checking any conditions.
- After executing the code block, the condition in the while statement is evaluated.
- If the condition evaluates to true, the code block is executed again. The loop continues until the condition becomes false.
- If the condition initially evaluates to false, the code block is still executed once before exiting the loop.
