defer vs async keyword in script tags
Hello, quick question, I know that both
On the other hand, the
I always make use of the
defer and async will load our external javascript file at the same time as our HTML parser is working. The difference is that defer will only be "triggered" after the HTML parser has been completed.On the other hand, the
async keyword would mean that "run the external file whether or not the HTML parser has completed".I always make use of the
defer keyword, so I wanted to know some use cases where async is used, any idea please.
