old school (internet explorer), you need to change as the previous answers stated
var person={
first_name:"John",
last_name:"doe",
id:5577,
// ^ missing comma
fullName: function(){
// ^ missing colon
return this.first_name+" "+this.last_name;
}
}
ES2015 (ES6) has a shorthand
var person={
first_name:"John",
last_name:"doe",
id:5577,
// ^ missing comma
fullName(){
// ^ no need for "function" keyword
return this.first_name+" "+this.last_name;
}
}
