 In a previous episode we talked about how jQuery augmented the API of DOM elements to make the developers life easier when it came to the management of CSS classes. Another popular API that jQuery offered was Closest, which returns the closest ancestor of the current element which matches the selector. For example, this is very useful in having a reference to a certain button or input field and wanting to get a hold of the enclosing form element. It is so useful in a fact that the web platform now offers the exact same function directly on DOM elements. All modern browsers offer this API and it can be polyfilled with a couple of lines of code if necessary. The fact that so many APIs of jQuery influenced the web platform itself shows that the jQuery authors were real web developers that solved real problems. What would you like to know more about?
