The first loop is often called an "outer loop", and the second is often called the "inner loop" because it is inside the first, outer loop.</p><p>The outer loop executes first, and for each time the outer loop is executed, the inner loop will also execute.</p><button onclick="myFunction()">Try it</button><p id="demo"></p><script>function myFunction() { var text = ""; var i, j; for (i = 0; i < 3; i++) { text += "<br>" + "i = " + i + ", j = "; for (j = 10; j < 15; j++) { document.getElementById("demo").innerHTML = text += j + " "; } }}</script></body><!-- Mirrored from www.w3schools.com/jsref/tryit.asp?filename=tryjsref_state_for_nested by HTTrack Website Copier/3.x [XR&CO'2014], Wed, 05 Jun 2019 14:02:45 GMT --></html>
