Meaning of syntax in JavaScript

Question

What is the meaning of this syntax "x?x&&y?y", i tried to figure it out but didn't have any clues. Thanks in advance.

Answer 1

Where are you seeing that at?

'?' is the ternary operator in Javascript (as well as most languages). Basically, it allows you to shorten your IF/ELSE statement into one simple expression.

EXAMPLE:

var result = 5 < 10 ? "True" : "False";

^As you can see, it's simplified what we would have done with an IF statement. The syntax is as follows: (condition) ? (expression if true) : (expression if false)

&& - That simply means AND. It is used for multiple conditions which require both conditions to be true.

EXAMPLE: IF (2 > 1 && 5 < 10) { }

Hopefully this helps explain it to you.
