Hello Folks 👋

What's up, this is SnowBit here. I am a young passionate and self-taught developer and have an intention to become a successful developer.

Today, I am here with a basic topic mostly for beginners and revisers.

Avoid this 

const arr = ["JS", "PY", "CSS"]
const lastItem = arr[2]

Don't do this for getting the last item of an array. Let me explain, this is a small array and contains only 3 items that are easily countable but, what if there are hundred's of items in an array then this method will make you mad 🤯

Do this 

const arr = ["JS", "PY", "CSS"]
const lastItem = arr[arr.length - 1]

Here, arr.length becomes dynamic, it increases as you increase items in arr no matter how many you add and that will not make you mad 😜

Thank you for reading, have a nice day!
Your appreciation is my motivation 😊
