JSLint imposes us to do manual hoisting of variables. What if we did it but at the end of the function? 😛
How you write
function print_array (array) { var length = array.length; for (var i = 0; i < length; ++i) { var elem = array[i]; console.log(elem); } } |
How Javascript “rewrites” it
function print_array (array) { var length, elem, i; length = array.length; for (i = 0; i < length; ++i) { elem = array[i]; console.log(elem); } } |
length = array.length;
for (i = 0; i < length; ++i) {
elem = array[i];
console.log(elem);
}
}
How we could write it!
function print_array (array) { length = array.length; for (i = 0; i < length; ++i) { elem = array[i]; console.log(elem); } var length, elem, i; } |
var length, elem, i;
}
$(‘.highlightvar span:contains(var)’).css(‘background-color’, ‘yellow’).css(‘color’, ‘red’)
I have no idea if that could be of any use but it amused me 🙂
