how to do this help me

To count the for loop's iterations, declare a variable, track the count, and increment it within the loop.

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

let b = 10;
let count = 0;
for (let a = 1; a <= b; a++) {
  console.log(a);
  count++;
}
console.log("count =", count);

<!-- end snippet -->
