Avoid the “delete” Keyword in JavaScript
Hello Folks 👋
What’s up, friends? This is SnowBit here. I am a young, passionate and self-taught front-end web developer with an intention to become a successful one.
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.
Thank you for reading, have a nice day! Your appreciation is my motivation. 😊
