Question

I want to reverse the string like this: "How are you" -> "you are How"
Those are the code I typed, it could reverse the string ,
but it still has comma between strings like "you,are,How"

var str = window.prompt("Enter a string");
var tokens = str.split( " " );


document.writeln( tokens.reverse() );

Answer 1

Use .join(” “)

var str = window.prompt("Enter a string"); var tokens = str.split( " " );
document.writeln( tokens.reverse().join(" ") );
