In computability theory, the Ackermann function, named after Wilhelm Ackermann, is one of the simplest and earliest-discovered examples of a total computable function that is not primitive recursive. All primitive recursive functions are total and computable, but the Ackermann function illustrates that not all total computable functions are primitive recursive.

What is lazy loading?
With lazy loading you could delay a particular elements loading until a time that it’s actually required. In case it’s never required like if the user does not scroll to that part of the page, wouldn’t it be ideal to not load that element at all?
The main goal here is utilizing this to make the webpage faster overall.
How does lazy loading technically work?
Lazy loading is just a concept and can be accomplished by multiple techniques. For images, the most common way it is done is by using an
img with a dummy
Does lazy loading affect SEO?
TLDR; Yes! Google bot won’t cache those objects. Won’t be indexed.
