Union of Two Arrays in Javascript is the today topic of discussion in this tutorial.
Algorithm of Union of Two Arrays in Javascript
- Initialize Two Array: ( Array1 and Array2 with values)
- Initialize result [ ] as empty.
- Initialize and obj { } as empty.
- Copy all elements of Array1 to obj.

{

}
for(const x in obj)
{
result.push(x);
}
return result; //return result

Output
