Repl.it Code Editor

JavaScript
1

Does anybody know how to comment a syntax of code in repl.it editor ??

2

What do you mean with “comment”?

In JavaScript you can always add comments with // in front of it

All languages have their own way to add comments

3

in which language? it’s not specific to the editor, it’s specific to the language. Probably //

Yes Guyz I am asking for javascript syntax. When I write code in repl.it for practise, suppose now I want to write another code of lines for that I need to comment the previous one. But, when I select code and comment it by using // it deletes it. Is there any short cut or method for it ?? I saw some tutorials videos of javascript in which the lecturer just select the code and press // it comments it. But in my case it deletes the code.

you need to add // in front of the code, not select and then type

or if you have a block of code you want to comment (as in more than one line) write /*before and */ after the block of code

6

and if you right click and choose “Command Palette” it will show you all the shortcuts you can use

@ilenia I am not getting ur first point. suppose I want to comment a block of code then I’ll need to just go on the first line of code and need to add //. Isn’t like that ??

If you use // then the rest of the line is commented out
If you want different lines commented out you need to add /* at the beginning and */ at the end

// this is a signle-line comment

/* this is
a multi-line
comment */

He is saying to comment a block of code, format looks like this:
/*
Block
Of
Code
*/

Or for single line:
// line of code

Yes I get and I go with second option every time. But I’ve seen in many video tutorials lecturer just select the code and press //. The entire code will be commented. Sorting out how to do that. Will share video then might u can see and sort it out.

11

They certainly don’t use just // as a shortcut
Check the command palette (right click -> command palette)
I remember something like below but I may be completely wrong as I don’t have it in front on me
The short cut for single line comment is Ctrl+K Ctlr+C

12

Really? It should be Ctrl+/

13

It is in the Command Palette of the editor… I didn’t choose it myself

14

Ctrl+K Ctrl+C adds // to the beginning, Ctrl+/ toggles comment. Ctrl+/ is the more common one too
And easier to press.

Thank you guyz for helping me out. :slight_smile:

We can use both either ctrl+/ or ctrl+k ctrl+c

16

But if you want to toggle, use Ctrl+/
