Steamroller without recursive! using 'splice' and 'spread' operator =)

[customxvega]

i want yours help to evaluate if this method may be called recursive or not , the test Steamroller agree it :

function steamrollArray(arr) {
for(let i=0;i<arr.length;i++){            //1
if(Array.isArray(arr[i])){                     //2
arr.splice(i,1,...arr[i])
if(Array.isArray(arr[i])){                     //3
i=i-1}                                           
}}
return arr
}

steamrollArray([1, [2], [3, [[4]]]]);

1 iterate trough array
2 if ‘arr[i]’ value is array ,replace at same position with spread operator’…arr[i]’
3 another ‘if’ function to check if ‘arr[i]’ still an array,if it’s not, back one step ‘i’ to reiterate trough the same index until ‘arr[i]’ became a non array value .
i dedicate this code to FreeCodeCamp Team =)

The function is not called inside of the function, so no, it isn’t recursive.

This will only work for arrays with two levels of depth.

This will only work for arrays with two levels of depth.

i try it on multiple depth, it work well .

@customxvega

i=i-1

Oh. It’s working because of this. This is an anti-pattern with for loops.
