JS 1999 (ES3)
The 1999 edition is part of JavaScript history. Older code often uses var and constructor functions rather than modern class syntax.
Where to run this

A practical example
function Member(name) { this.name = name; }
var member = new Member("Mira");
console.log(member.name);
What happens
