comes from an interview question. I haven"t thought about it for a long time.
the title is as follows
function fill (n, m) {
//
}
console.log(fill(3, 4)) // [4,4,4]to implement
with recursionPlease let me know!

function fill (n, m) {
n--
if(n) {
return [m].concat(fill(n, m))
} else {
return m
}
}PS: Array.prototype.fill () method is not like this.
first of all, you need to know the fill implementation of array, file (v [, start [, end]]) where v is the value to be replaced, start is the start position, and end is the end position, that is, elements from start to end are always replaced with v in the array.
if you ask for the title, this is not the case at all.
