Is there a JavaScript equivalent of the Python pass statement that does nothing?

Question

I am looking for a JavaScript equivalent of the Python:

pass statement that does not run the function of the ... notation?

Is the

Answer 1

In some cases pass can just be ;

A real life example can be:

var j;
for (j = i + 1; j < binstrN.length && binstrN[j] != 1; j++) {
}
let count = j - i;

is same as

var j;
for (j = i + 1; j < binstrN.length && binstrN[j] != 1; j++);
let count = j - i;

Here we are trying to move j to next '1', while i was already at a '1' before it, hence count gives the distance between first two '1's in the string binary string binstrN

Answer 2

use //pass like python's pass

like:

if(condition){
   //pass
}

This is equivalent to leaving the block with nothing in it, but is good for readability reasons.

Answer 3

If you want to just use the pass operator in a ternary operator or just in an if statement in JS, you can do this:

a === true && console.log('okay')

You can use also use || operator but you should know that the || is the opposite of &&. Then if you want to use Pass in a function or a block in general as we do in Python like this:

def Func(): pass

In JS you should just leave the block empty as this:

 if(){ 
    console.log('ok')
    }else{}

In the end, there are no braces in Python, so this is the main reason why we have a pass.
