Array Arrangement Permutation

Question

Looking for a way to sequentially find different arrangement possibilities of an array. I only care about adding them sequentially, doesn\'t need skip or shuffle values.

Answer 1

You could iterate over each character once and should be able to populate all sequences.

Here is what you could do.

var inputArray = ['a', 'b', 'c', 'd', 'e', 'f'];

var outputStrings = [];

inputArray.forEach((item, idx) => {
  let prevString = (idx !== 0) ? outputStrings[idx - 1] : "";
  outputStrings.push(prevString + item);
});

console.log(outputStrings);
