JS : CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Question

For higher input it not works it gives fatal error : CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory what i do for running the same algorithm (that means using the recursion) and it successfully runs not gives the heap out of memory

/*CREATE THE ALL POSSIBLE PERMUTATION OF STRING.*/
var counter = 0;

function permutation(str, start, end) {

else
    for (let i = start; i < end; i++) {
        str = swap(str, start, i);
        permutation(str, start + 1, end);
    }
