JavaScript Simplified - Chapter 81 Exercises

A function that creates objects is a (one word)_______

constructor

Fill in the blank. Make up the name. (Remember the naming convention for this type of function.

function _______(name, area, population) {

The first character is capitalized: Nation not nation

[A-Z][a-zA-Z0-9_$]*

The constructor's name is Student. Fill in the blank to call it.

const student404 = ____________("Sigel", "Efrem", 12, 89);

new Student

newStudent

The name of the constructor is Planet. Code the first line of the function, including the parameters distance and mass.

function Planet(distance, mass) {

functionPlanet$distance,mass${

The name of the constructor is Planet. Code the complete function, including the parameters distance and mass. The property names are the same as the parameter names.

function Planet(distance, mass) {
this.distance = distance;
this.mass = mass;
}

functionPlanet$distance,mass${[\r\n]this\.distance=distance;[\r\n]this\.mass=mass;[\r\n]}

Code a constructor function that has a single parameter. The property name is not the same as the parameter name. Make up all the names.

function Patient(x) {
this.age = x;
}

function[A-Z][a-zA-Z0-9_$]*$([a-z_$][a-zA-Z0-9_$]*)${[\r\n]this\.[a-z_$][a-zA-Z0-9_$]*=\1;[\r\n]}

Create an object by calling a constructor named Product. Include two arguments, the product's name and the product's color. Make up everything except the constructor function name.

const sku2191 = new Product("frisbee", "white");

const[a-z_$][a-zA-Z0-9_$]*=newProduct$•.*•,•.*•$;

Code a constructor function with two parameters. The names of the parameters and the names of the properties are the same. Make up everything.

function Vehicle(make, model) {
this.make = make;
this.model = model;
}

function[A-Z][a-zA-Z0-9_$]*$([a-z_$][a-zA-Z0-9_$]*),([a-z_$][a-zA-Z0-9_$]*)${[\r\n]this\.\1=\1;[\r\n]this\.\2=\2;[\r\n]}

I've coded a constructor.
Use the constructor to create an object.
Display the value of one of the properties of the object in an alert.
Wait a moment.
If you've coded correctly, an alert will display the property value.
Dismiss the alert by clicking OK.
For help with this code, see Chapter in the book.

Code a constructor that creates objects that have three properties. Give the properties different names from the parameter names.
Call the constructor.
