ES6 has given us Sets, a list type that is kinda like arrays, but better, mainly because Sets automatically don't allow duplicates, so list management just got a whole lot easier.
USAGE: Copy and paste the code samples below into the Javascript console in your browser, then simply hit return on your keyboard to see the code in action.
//Sets
//A list of unique values (arrays can contain duplicate values, sets only contain unique values
//(easier to manage then arrays))
let set = new Set([1, 1, 1]);
console.log("New set: " + set);
set.add(15);
console.log('does set contain 15? ' + set.has(15));
for (element of set) {
console.log(element);
}
//Sets (sorta like CF structs)
let names = new Set();
names
.add("Mike")
.add("Rich")
.add("Bob")
.add("Dave")
.add("Fred");
console.log("size of this set is:" + " " + names.size);
names.delete("Fred");
console.log("size of this set is:" + " " + names.size);
console.log(names.has("Rich"));
names.clear();
console.log("size of this set is:" + " " + names.size);
//More sets (duplicates)
let bros = ["Mike", "Rich", "Bob", "Dave", "Dave", "Mike"];
let refinedBros = new Set(bros);
console.log('refinedBros: ' +refinedBros);
//the spread operator adds elements into an array
bros = [...refinedBros];
console.log("Final list: " + bros);
