Arrays are used to solve most of the coding problems. So when starting with this, there raises a question for everyone i.e “What are the possible w...

Thanks for the article - it certainly does cover off all of the methods.
I'm just about to write on this subject myself - and having just been researching:
Firstly your first examples don't seem to line up e.g. (1) says its a
for(;;)loop, but your example isn't - it's some kind of filter. There are a couple of others that are also not what the title says.Secondly
for(;;)loops are held to be fastest - and jsPerf and jsBench.me will tell you that. But run it in your own browser or codesandbox and you may be in for a surprise.Thirdly - reading the length every iteration doesn't appear to make any difference, in fact it can be faster because modern browser Javascript engines optimise for it. They know that JS is single threaded and spot the pattern.
foris the fastest one over all others. Thanks for listing out these points.Your third point is interesting I had wondered about this in the past. Off to look further into this!
All the 8 ways given above to Iterating arrays in javascript are fabulous. Thanks for shring such a good information, it helped me a lot.
