Javascript Beginner's Array Exercises: Finding elements in an array

In this video about arrays in Javascript we find the number of integer elements in an array that are >= 10.

Here is the important part of the source code:

// 1: Given an integer array: The program must compute and write how many integers are greater than or equal to 10.

var arNums = [76,42,2,3,5,6,2,56,777,9,0,5,2,56,1];

var intsGTE10 = 0;
for(let i = 0; i < arNums.length; i++) {
  if(arNums[i] >= 10) {
    intsGTE10++;
  }
}
