Is your code clumsy? or do you need to avoid certain code steps in-between? In Javascript, we have a comment option just like any other programming language. We can comment a code using two ways :
- Single line comment (//)
- Multi-line comment(/* */)
1. Single line comment
A Single-line comment comments out a solo line in a code.
Example:
console.log("Hello World")
//console.log("Hello World") 2. Multi-line Comment
- A Multi-line comment comments out multiple lines of code.
- Using /* before a code comments out the rest of the code you are writing down to the point of infinite.
- Use */ up to the point of code you want the comment to end and continue normal coding afterward.
Example:
/*
let k=2;
let f=3;
let g=k+f;
console.log(g)
*/
console.log("Uncommented") Why Comments?
- In any programming, language comments are used to prevent any unwanted executions and make the code more readable.
- In the comments, you can also give what the code is about as a description.
- You can simply use comments and write pseudocode to actually take reference on what you are doing.
- With Comments, you can notify and explain to any people with less knowledge on coding what actually you are doing in the code.
- Comments are a big stress relief for yourself to review the code after a long time.
