Example and explanation of JavaScript namespaces tree.
The following namespaces need to be defined in JavaScript:
root
root.person
root.home
root.home.relative
My attempt that was incorrect:
var root='';
root.person='';
root.home='';
root.home.relative='';
Please provide an explanation for your code as I am not very familiar with JavaScript compared to PHP or Java.
Thank you!
When working with JavaScript, we don't have the concept of "namespaces" like in Java. Instead, we rely on using objects and adding attributes to those objects.
If you want a sort of "namespace" called root, you can create an object named root and then add different members to it such as "person", "home", and "relative".
To define an object for the root namespace, a simple way is to use the object literal syntax.
var root = {
person: 'Jim',
home: 'London'
}
You can also nest objects by using this syntax, which allows you to create nested objects like having a nested relative object:
var root = {
person: {
'first_name': 'Matt',
'last_name': 'Smith'
},
home: {
relative: 'Frank'
}
}
It seems like there might be some confusion on what you're looking for, but are you referring to this concept:
let main = {};
main.character = '';
main.world = {};
main.world.envisioned = '';
If you're aiming to add additional properties dynamically to an object, rather than just a single value, it's best to initialize it as an empty object literal
let item = {}; item.subItem = {};When it comes to nesting properties, it's important to define the variable as an object rather than just a string:
let container = {};
container.item = '';
container.room = {};
container.room.furniture = '';
console.log(container);
If you're utilizing Firebug, the console.log function will neatly display your object hierarchy.
