So the idea is to create a class Animal and the set properties to it as a new object
Here is what I have:
var name;
var type;
function Animal(name,type){
this.type = type,
this.name = name,
toString = function(){return this.name + "is a " + this.type;}
};
var cat = new Animal('Max','cat');
cat.type;
everytime I run it - I seem to fail at the toString part? Pretty new and trying to learn this - is there something I am missing?
You don't need to declare those top variables, the arguments should be local to the function. The syntax is wrong too, you should use semicolons, not commas, and toString becomes a global variable since you forgot to use var.
What you want is this.toString so this works inside and refers to the instance, or better yet, create a method on the prototype so it's re-usable for all instances of Animal:
function Animal(name,type) {
this.type = type;
this.name = name;
}
Animal.prototype.toString = function() {
return this.name + "is a " + this.type;
};
function Animal(name, type) {
this.type = type;
this.name = name;
};
Animal.prototype.toString = function() {
return this.name + "is a " + this.type;
}
var cat = new Animal('Max', 'cat');
console.log(cat); // Prints "Max is a cat"
