Sometimes I hate how in order to make things efficient (?), the code
size becomes really huge:
var getText = (function(){
var type = document.createElement('div');
if (typeof element.textContent != 'undefined') {
return function(element) {
return element.textContent;
}
}
else if (typeof element.innerText != 'undefined') {
return function(element) {
return element.innerText;
}
}
return function(){};
})();
