I have an array of numbers and would like to generate all possible combinations with 2 numbers as shown in the expected
const numbers = [1,2,3];
Expected:
const result = [
[1,2],
[1,3],
[2,1],
[2,3],
[3,1],
[3,2]
]
let num = [1,2,3];
let arr = [];
for(let i=0; i<num.length; i++){
for(let j=0; j<num.length; j++){
if(j === i) continue;
arr.push([num[i], num[j]]);
}
}
console.log(arr);
