I would like to use generator to print the content of an array, however yield inside another yield is confusing to me
let myArray = ["a", "b", "c"]
function* line(array){
yield "my array"
array.forEach(function*(v){yield v})
}
console.log(Array.from(line(myArray)))is there a way to print the "a", "b" and "c" each in a new line with the code above?
expected output
my array
a
b
c
>Solution :
Being explicit, with a visible inner for(of):
let myArray = ["a", "b", "c"]
function* line(array) {
yield "my array";
for( const ch of array ) {
yield ch;
}
}
console.log(Array.from(line(myArray)))Using implicit iteration with yield*:
let myArray = ["a", "b", "c"]
function* line(array) {
yield "my array";
yield* array;
}
console.log(Array.from(line(myArray)))…basically, yield* $iterable; is the same thing as doing for( const v of $iterable ) yield v;.
