I want to convert JavaScript Set to string with space.
For example, if I have a set like:
var foo = new Set();
foo.add('hello');
foo.add('world');
foo.add('JavaScript');
And I'd like to print the string from the set: hello world JavaScript (space between each element).
I tried below codes but they are not working:
foo.toString(); // Not working
String(foo); // Not working
Is there simplest and easiest way to convert from Set to string?
You can iterate through the set and build an array of the elements and return the desired string by joining the array.
var foo = new Set();
foo.add('hello');
foo.add('world');
foo.add('JavaScript');
let strArray = [];
for(str of foo){
strArray.push(str);
}
console.log(strArray.join(" "));
