TypeScript - do…while loop



The do…while loop is similar to the while loop except that the do...while loop doesn’t evaluate the condition for the first time the loop executes. However, the condition is evaluated for the subsequent iterations. In other words, the code block will be executed at least once in a do…while loop.

Syntax

do {
   //statements 
} while(condition)

Flowchart

Do While

Example: do…while

var n:number = 10;
do { 
   console.log(n); 
   n--; 
} while(n>=0); 

On compiling, it will generate following JavaScript code −

//Generated by typescript 1.8.10
var n = 10;
do {
   console.log(n);
   n--;
} while (n >= 0);

The example prints numbers from 0 to 10 in the reverse order.
