such as the title: often see other people writing code like to return the function as a return value
var res = test()
console.log((res.next())())
function test() {
var a = 10;
return {
next(){
return function () {
return a+1
}
}
}
}
I think writing like this will solve the problem:
var res = test()
console.log(res)
function test() {
var a = 10;
return a+1
} what are the advantages of the first way of writing? What are the usage scenarios?
