Javascript one line If, only state true

Question

In default 'if' one line statement are two block, for true, and false:

variable ? true block : false block;

How declare 'if' with one block?

I expect something like this:

variable ? true block;

Solution 1

if(variable) block;

With the conditional operator you need the false bit also.

Solution 2

You can do:

variable && block

For example:

let variable = true;
let o = variable && 3;

is it right to pass just null for the false block, when we use the ternary?

You could. I wouldn't use it. I use ternary when I know I have 2 operations. If just care about the true or false condition I would use it this way. It's more a preference then anything @CeylanMumunKocabaş

Edited @RobG. Thanks for the correction ;)

@CeylanMumunKocabaş—you can do that, but it's more to type and not as clear as using a simple if.
