Today I have been learning about arrow functions. I've got to say that at first it's hard to wrap my head around the idea that a function can take ...

.someand.everyare amazing too, also.reduce. All the functors rock. AlsoArray.fromThis is a nifty trick too, pass a
Booleanconstrutor to clean an array of all falsely or holes, return only truthy values.Lastly
.findis just like filter but returns one value rather than an array.Ps.
I think all the functors are based on
reduce.PSS.
This is functional programming where this expression is preferred over statements like
ifandfor. You will be surprised how much you can get away with.Ooh! New toys! I'll have to check them and see what they do.
Incredible how there's still things to learn. I will definitely start looking at ways to through in this nifty trick, and that
.findtoo! Thanks!Looks like I should do a post on JavaScript arrays
They're amazing. Not a day goes by without me writing one of these! I love how easy they are to write and how understandable they are to read afterwards to know what a piece of code does.
I was about to say that, if you like map and filter, you'll love reduce, but it's been said...
I've looked at it a bit, but I think it'll be tomorrow's trouble, hehe
It'll be there when you get to it.
In my language of choice, Perl,
mapexists,filterisgrep, andreducecomes from a non-standard library. It still fills me with joy.Groovy well that's straightend out. 😅
Good explanation and examples! 😊
The explanation was neat!
These are my enemies from today onwards.. haha
