Out of curiosity, I'd like to see if there's a better answer than what's below. How can I convert this:
def counter():
ctr = 0
def inner():
ctr += 1
return ctr
return inner
counter = counter()
into this javascript equivalent?
counter = (function() {
let ctr = 0;
return function() {
return ++ctr;
} //inner anonymous func
})(); //outer func, called and forgotten, sort of.
The python above is fine, I was just curious if there was a faster/more readable way to do this.
To be clear, I don't want the outer factory function to be available after its called, and I want it to be called as soon as its defined. Think of it as a closure singleton. Thanks!
