Hey there, web developer extraordinaire! So, you've just used querySelectorAll() and found yourself staring at a NodeList?

• The "Slice and Dice" Approach
• The "Spread 'Em Out" Method
• The "From() Zero to Hero" Technique
• The "Array.from() For the Win" Wizardry

The "Slice and Dice" Approach

const nodeList = document.querySelectorAll('.elements');
const array = Array.prototype.slice.call(nodeList);

This method is as simple as grabbing a knife in a kitchen brawl. You borrow Array.prototype.slice to perform the transformation. Just make sure not to hurt any innocent potatoes in the process!

The "Spread ‘Em Out" Method

const nodeList = document.querySelectorAll('.elements');
const array = [...nodeList];

Here, we use the spread operator to swiftly spread out the contents of the NodeList into an array. It's like giving them a breath of fresh air!

The "From() Zero to Hero" Technique

const nodeList = document.querySelectorAll('.elements');
const array = Array.from(nodeList);

With the Array.from() method, we create an array out of the NodeList. It's like a magical transformation from zero to hero. Simple, elegant, and no animals harmed!

The "Array.from() For the Win" Wizardry

const nodeList = document.querySelectorAll('.elements');
const array = Array.from(nodeList, el => el.textContent);

This wizardry allows you to manipulate each element during the transformation. You can use an arrow function to extract specific properties, as shown above. It's like customizing your action heroes' superpowers!
