I need to find out if 2 arrays match (have common elements) in one or more elements.
Is there a more elegant way than the 2 loops?
In Java I would use a stream with lambda.
lst1.stream ().anyMatch (c -> lst2.contains (c))
But I am not sure hot to do that in Typescript/Javascript.
let lst1 : string [] = ["aaa", "bbb", "ccc"];
let lst2 : string [] = ["ddd", "eee", "bbb"]; // 1 match at "bbb"
let matches : boolean = false;
for (let a of this.lst1)
{
for (let b of this.lst2)
{
if (a == b)
{
matches = true;
}
}
}
