Use join:
string = s.join("");

@Digital_Pane: Thank you, this is exactly what I was looking for i.e. the string will be "Hello".
You do it this way:
var str = s.join();

Without an argument,
.join() will use "," as a default. But then OP didn't specify how it should be converted, so nothing wrong with your answer.moey
With
.join() i.e. without an argument, the string will be "H,e,l,l,o". Yes, as @patrick mentioned, since I didn't specifically stated what output I was looking for (actually, "Hello") this answer is still valid.The join command lets you set the token among the items in the array.
Ex1:
function print(str) { $("#result").append("<p>" + str + "</p>"); } print(["A", "B", "C"].join()); // "A,B,C" print(["A", "B", "C"].join("-")); // "A-B-C" print(["A", "B", "C"].join("||")); // "A||B||C" print(["A", "B", "C"].join("")); // "ABC"<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="result"></div>Comments
Or use String.
var string = String([1,2,3]);

That's the same as
s.toString() or any implicit conversion to string - unlikely to be what the OP asked for.If you have an array like let array1 = ['a', 'b', 'c'] you can try array1.join('') the ourput will be 'abc'
