如何检查一个字符串是否包含另一个字符串中的任何字符？

Question

How can I determine if any individual character in src matches any individual character in restricted ? I have this JS method which does the job, but I'd like to improve it if I can:

function CheckRestricted(src, restricted)
{
    for (var i = 0; i < src.length; i++)
    {
        for (var j = 0; j < restricted.length; j++)
        {
            if (src.charAt(i) == restricted.charAt(j))
                return false;
        }            
    }

    return true;
}

If this were C#, I could achieve this with LINQ in a single line:

bool CheckRestricted(string src, string restricted)
{
    return src.Any(s => restricted.Contains(s));
}

Is there some sort of similar functionality in JS that I'm unaware of?

EDIT: Sample use case:

CheckRestricted("ABCD", "!+-=;:'`"); //true
CheckRestricted("ABCD!", "!+-=;:'`"); //false

It is predominantly used to disallow 'special characters'.

Answer 1

function CheckRestricted(src, restricted) {
   return !src.split("").some(ch => restricted.indexOf(ch) !== -1);
}

Answer 2

No-loop solution.

 function CheckRestricted(src, restricted) { var a = [...src, ...restricted]; return [...new Set(a)].length == a.length; } console.log(CheckRestricted('word', 'abc')); console.log(CheckRestricted('word', 'wor'));
