Did you compare the performance of either in addition to considering the interface? Just because map can be more human readable doesn’t necessarily mean you shouldn’t use a for loop. for could be more performant for the end user.
Yes, sir totally agreed with you that the for loop is much faster than the other javascript array functions. Everything has pros and cons. so we have to choose wisely what to use in which situation
This is a very weak argument. I don't like the thinking that write whatever you wanna write because your pc's hardware can take it. Software is not in good place today because of that, especially web.
For and map have there own use cases. Use them wherever they suits the best.
From humble beginnings at an MSP, I've adventured through life as a sysadmin, into an engineer, and finally landed as a developer focused on fixing problems with automation.
I made it hidden by mistake. I am new at this platform so just testing some features, if you know how I can revert it, then plz tell about the procedure
You can easily get the performace metic on online b/w for and other functions . And every thing has pro and cons . I also has used for loop insted of the map in many situations
"Because performance" doesn't seem a particularly good argument to choose one option over another. How fast a for, map, etc will run depends on more than its name, like optimisations that the runtime can do. So just choosr whichever fits your needs and if you run into performance issues profile and see what's causing the bottleneck (which probably won't be that map that you chose to use instead of a for loop).

He's hiding any comments pointing out his weak arguments, so it makes sense. Terrible feature to be able to hide legitimate criticisms on DEV.
Ohh! I didn't know you can that.
This is sad 😔
I wonder why dev would make this feature 🤔

Do you have actual data to back that up?

Like this...

Oh, you mean those tests in which if you place forEach before for then forEach becomes faster? The same tests in which if you actually use the result of the operation afterwards map becomes faster than for?

This is what I mean. Engineers should consider performance when deciding which method to use.
