ViewsHow do arrange arrays with different combinations?
I have 3 arrays ["s","m"], ["Red","Black"], ["1", "2"]. I want to arrange them like this:
["s","Red","1"],
["s","Red","2"],
["s","Black","1"],
["s","Black","2"],
["m","Red","1"],
["m","Red","2"],
["m","Black","1"],
["m","Black","2"],
I'm out of idea, please help me.

Loop each one then just combine them into an array.
Script:
function test() {
arr1 = ["s","m"]
arr2 = ["Red","Black"]
arr3 = ["1", "2"]
arr1.forEach(x => {
arr2.forEach(y => {
arr3.forEach(z => {
console.log([x, y, z]);
});
});
});
}
Output:

let a = ["s","m"]
let b = ["Red","Black"]
let c = ["1", "2"]
for(let i = 0 ; i < a.length ; i++){
for(let j = 0 ; j < b.length ; j++){
for(let k = 0 ; k < c.length ; k++){
console.log(a[i], b[j], c[k])
}
}
}

you can make 3 nested loops, some thing like:
for (int i = 0; i<2; i++) {
for(int j = 0; j<2; j++) {
for(int k = 0; k<2; k++) {
//put your code here
}
}
}
