JavaScript Fun Question: Find the Murderer

A key witness was murdered. Before he died, he tried to name the murderer, but his voice was weak and intermittent, making it difficult to distinguish.

We obtained his recording, represented by a string. This string starts with a letter, and each "~" symbol represents an uncertain letter.

The length of the string does not mean the length of the name, because he may die before saying the murderer's full name.

The police provided a list of suspects and asked you to help find the murderer based on the recording.

The result should be a string. If not found, return an empty string. If multiple are found, please return these and separate them with commas.

	
	var suspects=['Bernard Deltheil','Peter Gone','Peter Reeves','Roland Scorsini']
	
	sc('b~~~~~~~~~~~~~~l',suspects); //'Bernard Deltheil'
	sc('p~t~r',suspects);			 //'Peter Gone,Peter Reeves'
	sc('a~b~c~~d',suspects);         //''

Note:

1. Match each suspect’s name, ignoring case.

2. The code should be as short as possible

For the following implementation, I used regular expressions to first replace the "~" symbol within the string with ".", and then use it as Part of the pattern, matched with the name.

function sc(s,a){
    var r = [];
    a.forEach((e)=>{if(new RegExp("^" + s.replace(/~/g,"."),"i").test(e))r.push(e);});
    return r.join(",");
}
