Is there a way to reduce the size of my code by calling functions with shorter aliases?
(function(){
var id = document.getElementById;
id('element-id');
})();
After making this change, an error message appears:
Error: Could not convert JavaScript argumentChanging the assigned function to a different variable causes its this value to change as well. This is why when getElementById expects this to refer to an element, an error occurs.
If you have access to bind in your environment, it can be used like this:
(function(){
var t = document.getElementById.bind(document);
t('element-id');
})();
By using this method, the this of t will remain bound to the document object.
If utilizing bind is not possible, you will need to create an intermediary function:
(function() {
function t (id) {
document.getElementById(id);
}
t('element-id');
})();
In Joseph's opinion, when the this value is altered, it can cause disruptions to the function. A possible solution to this issue is:
var selector = function(id) {return document.getElementById(id);};
If you find yourself in this situation, you have the option to use:
const getElement = (id) => document.getElementById(id);
getElement("myElement")
This utilizes an arrow function that acts similarly to
