I agree with all the point except for the first one. Chained Function Calls, there is no need to use extra memory space when we can use chaining.
But again, its individual perspective. Nice article.
I think now a days, we don't have to worry about memory. I would prefer to be able to read, debug and understand the code instead of having to worry about memory.
But for sure, I am talking about PHP. It might makes sense to worry about the usage of memory in different languages.
No offense, it's just I have a personal rule not to create an unwanted variable until that particular value is used more than ones.
You're right, not every function call must be wrapped in a variable. It always depends, right? 🙃
