- Create a Human constructor function that takes in a name and age.
- Add a prototype function ageOneYear that ages the humans age.
- Add a prototype function eating, that logs "mmm, mmm, mmm, I'm love'n it".
- Create an instance of the Human class.
- console log your humans age
- call ageOneYear on your human
- console log their age again.
- call eating on your human.
function Human(name,age){
this.name = name;
this.age = age;
}
let thomas = new Human("Thomas",30)
console.log(thomas);
Human.prototype.ageOneYear = function(){
this.age++;
return `One year has passed now I'm ${this.age}`
}
console.log(thomas.ageOneYear());
Human.prototype.eating = function(){
return "Just ate. Mmm, mmm, mmm, I'm love'n it."
}
console.log(thomas.eating());
Write a constructor Vector that represents a vector in two-dimensional space.
It takes two number arguments: x and y parameters, which it should be saved to properties of the same name.
Give the Vector prototype two methods, plus and minus, that take another vector as an argument and
returns a new vector that has the sum or difference of the two vectors’ (the one in this and the parameter) x and y values.
Add a method getLength to the prototype that computes the length of the vector ;
that is, the distance of the point (x, y) from the origin (0, 0).(a^2 + b^2 = c^2)
var v1 = new Vector(1, 2)
var v2 = new Vector(2, 3)
console.log(v1.plus(v2));
// => Vector {x: 3, y: 5}
console.log(v1.minus(v2));
// => Vector {x: -1, y: -1}
var v3 = new Vector(3, 4)
console.log(v3.getLength());
// => 5function Vector(x, y){
this.x = x;
this.y = y;
}
let v1 = new Vector(2,5)
let v2 = new Vector(3,7)
console.log(v1);
console.log(v2);
Vector.prototype.plus = function(vec){
let sum1 = this.x + vec.x
let sum2 = this.y + vec.y
return `x: ${sum1}, y: ${sum2}`
};
console.log(v1.plus(v2));
Vector.prototype.minus = function(vec){
let sum1 = this.x - vec.x
let sum2 = this.y - vec.y
return `x: ${sum1}, y: ${sum2}`
};
console.log(v1.minus(v2));
Vector.prototype.getLength = function(){
return Math.hypot(this.x, this.y)
}
let v3 = new Vector(3, 4)
console.log(v3);
console.log(v3.getLength());
