Why is JSHINT complaining that this is a strict violation?
I think this may be a duplicate of Strict Violation using this keyword and revealing module pattern
I have this code:
function gotoPage(s){
if(s<=this.d&&s>0){this.g=s; this.page((s-1)*this.p.size);}
}

Error message "Strict standards: Only variables should be passed by reference"
$el = array_shift($instance->find(..))
The above code somehow reports the strict standards warning, but this will not:
function get_arr(){
return array(1, 2);
}
$el = array_shift(get_arr());
So when will it report the warning anyway?

In ECMAScript5, what's the scope of "use strict"?
What scope does the strict mode pragma have in ECMAScript5?

JavaScript: Can ECMAScript 5's Strict Mode ("use strict") be enabled using single quotes ('use strict')?
JavaScript doesn't care if your Strings are double-quoted "double" or single-quoted 'single'.
Every example of ECMAScript 5's strict mode has it enabled by "use strict" in double-quotes. Can I do the following (single-quotes):
