You use the flat() method for concatenating sub-arrays recursively into a single array. The flat() method takes a depth value as its parameter which is optional depending on the depth of the array you wish to flatten (concatenate). The flat() method takes in 1 as a depth by default.
The flat() method creates a new array with all sub-array elements concatenated into it recursively up to the specified depth.
The flatMap() method returns a new array formed by applying a given callback function to each element of the array, and then flattening the result by one level.
IE does not support Array.prototype.flat(). you can use reduce and concat as a workaround:
childs = childs.reduce((acc, val) => acc.concat(val), [])
