As a project grows the load time of pages will slowly increase. Many people look to the back-end for solutions to this problem, when in reality the way JavaScript is loaded can make a large difference in page load speed. In this video, I will look at the three ways to load JavaScript, normal script tags, async script tags, and defer script tags. I will cover the following topics:
1. What is Async and defer?
2. Difference between async and defer attributes?
3. When should I use defer over async?
4. Examples of scenarios covering async and defer
By the end of this video, you will have a strong understanding of the various ways to load JavaScript and will be better equipped to make faster and more responsive pages.
