Every JavaScript Dev Should Know This (Defer Attribute)

In today's video we're going to take a look at the 'defer' attribute in HTML and JavaScript. This can be used to increase the quality of code on your website, and resolve some errors 🙂

This can be used to resolve the "cannot read properties of null" JavaScript error.

Worth to add: "the defer attribute has no effect on module scripts — they defer by default." (MDN)

Thanks for the video. Is defer the same as "DOMContentLoaded"?

[MahbubTonoy]

Hi! Great video, how do you execute inline js placed on a script tag on the page at the bottom, that need the defer files on the header to be loaded first? how is the order of execution and how to make shure that the defer files are loaded before execution of the bottom scripts on the page? thanks.

You're the best at programming. I like you so much 😎

Does it make sense to add defer if external script is added in body?

Bro could you make a video about how to create a loading section before the data from an api is rendered and render error when there is a problem with the api using fetch api with async await in react.
