Can i use multiple line in ternary operator-CodePudding

I want to use the if else statement in the ternary operator

     if (open) {
         setOpen(false)
     } else {
         setOpen(true)
         navigator.clipboard.writeText(link)
     }

There is no problem in "if" I cant figuring out how to convert else to ternary. Like something the code below:

open ? setOpen(false) : setOpen(true) ; navigator.clipboard.writeText(link)

Something like this or is there another method to do the job?

Don't.

You're trying to use the ternary conditional operator for the wrong reason. It is not a drop-in replacement for any if block.

The ternary conditional operator is an expression. It resolves to a value, which can be used elsewhere. For example:

let x = someCondition ? 1 : 0;

The expression resolves to a value, either 1 or 0, and that value is used in an assignment statement.

The code you're showing is not an expression. What you have is a series of statements, conditionally executed based on some value. An if block is a structure for conditionally executing statements.

The code you have now is correct.

CodePudding user response：

Yes, it's possible to write multiple statements in ternary if else cases:

The format is:

condition ? codeLine1 : ( codeLine2 , codeLine3 )

Which makes your statement as:

open ? setOpen(false) : (setOpen(true), navigator.clipboard.writeText(link));

Combine multiple statements in parenthesis separated by commas in between each line.

That being said it's recommended to use old fashioned way of if-else statement if multiple statements are involved.

Please select answer if it helps and let me know if any questions.
