Question

I want to ask mean of plus operator in this script +i+ in the follow:

i=0;
// next line in scripts write this code :
$('.container[data-id='+i+']').hide(); // +i+ what the meaning of it

Need Help thanks a TON

Answer 1

+ is used to concatenate strings

In this case, it is used to concatenate the value of ibetween .container[data-id= and ]

Assuming that i is storing some value eg 0, then this will be evaluated to

$('.container[data-id=0]').hide();
