Avoid the "delete" keyword in Javascript

Hello Folks 👋

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

Today, I am here with an interesting and important topic. So, let's get ready to dive into the topic. Happy Reading!

const snowbit = {
    age: 15,
    test: "abc"
}
delete snowbit.test

console.log(snowbit) // {age: 15}

Here, it's better not to use delete to remove the property from the object snowbit.

Let me explain, You should not use delete to remove the property from the object because this mutates the original and that can lead to unpredictable behaviours and becomes difficult to debug.

Instead, use the spread operator to create a new copy.

const snowbit = {
    age: 15,
    test: "abc"
}

const {test, ...newSnowbit} = snowbit

console.log(newSnowbit) //  {age: 15}

Stay tuned for the next article, and make sure to follow if you haven't.
