What is the best way to transform an array containing double sets of brackets into a single set of brackets?

Is there a way to change the format of this list

[[" ", " ", " ", " ", " ", " ", " ", " ", " ", " "]]
to look like
[" ", " ", " ", " ", " ", " ", " ", " ", " ", " "]
?

I recently added an array within another array, but now I want to remove the outer brackets from it. Any suggestions on how to do this?

Currently searching for a suitable method to achieve this.

let ii :any[]=[];
const i =  ' '.repeat(10) ;
const d =  i.split('')   ; 
const aa=ii.push(d);
console.log(ii,ii.length);
console.log(d,d.length ); 

Answer №1

Modern JavaScript environments now have built-in support for the flat() method.

const flatData = [["a", "b", ["c", "d"]]].flat(2)
console.log(flatData)
// ["a", "b", "c", "d"]

You can specify a number as an optional parameter in the flat() method to determine how many levels of nested arrays should be flattened.
