Learn how to convert a multi-dimensional array into single dimension array in javascript
We can flatten an array to single dimension array using Array.flat(depth) method.
But if we have multi-dimensional array then we need to find the depth of the Array, instead of finding depth we can solve the problem in two ways
we can pass Infinity as depth ,
Input : [1,2,3, [2,3,[1,2,[3,4]],4,5,6]];
Expected Output : [1,2,3,2,3,1,2,3,4,4,5,6]
Consider we have input and result array .
We can loop through each element in input array,
If
- current element is not an array then push the element into the
resultarray, - current element is an array then again loop through all the elements of the current element , if we have another array then call the same function recursively .
There is another simple way to do the same using the string split method,
var a = [1,2,3, [1,2, [1,2, [1,2] ] ] ];
a = a + ""; // results in --> 1,2,3,1,2,1,2,1,2
a = a.split(','); // ["1", "2", "3", "1", "2", "1", "2", "1", "2"]
But all the elements are converted to string , if it is not a problem then we can use this method.
