Pure JS equivalent of Jquery eq

Question

What is the pure equivalent of jquery's eq(). For example, how may I achieve

$(".class1.class2").eq(0).text(1254);

in pure javascript?

Answer 1

To get the element index in the array you can use [] in javascript. So to reproduce your code you can use this:

document.querySelectorAll('.class1.class2')[0].textContent = 1254;
