In JavaScript, you can iterate through a NodeList (a collection of nodes returned by methods like querySelectorAll, getElementsByClassName, getElementsByTagName, etc.) using several methods. Here are a few common ones:

1. Using a for loop:

var nodes = document.querySelectorAll('.your-class');

// Using a for loop
for (var i = 0; i < nodes.length; i++) {
    console.log(nodes[i]);
}

2. Using forEach method:

Please note that NodeList.forEach is not supported in older browsers (IE, Edge < 18). If you need to support older browsers, you should use a regular for loop or Array's forEach method with Array.from() or [...spread] operator.

var nodes = document.querySelectorAll('.your-class');

// Using forEach
nodes.forEach(function(node) {
    console.log(node);
});

3. Using for...of loop:

for...of loop is also not supported in older browsers (IE, Edge < 15).

var nodes = document.querySelectorAll('.your-class');

// Using for...of
for (let node of nodes) {
    console.log(node);
}

4. Converting NodeList to an array:

You can use Array.from() or [...spread] operator to convert NodeList to an array and then use any of the array methods.

var nodes = document.querySelectorAll('.your-class');

// Using Array.from()
Array.from(nodes).forEach(function(node) {
    console.log(node);
});

var nodes = document.querySelectorAll('.your-class');

// Using spread operator
[...nodes].forEach(function(node) {
    console.log(node);
});
