# Description
|
|
|
|
Values of the type [object](20200826201605-objects) are arbitrary
|
|
collections of properties
|
|
|
|
# Syntax
|
|
|
|
``` javascript
|
|
let tralala = {
|
|
distro: "Arch",
|
|
useWindows: false,
|
|
aListOfRandomThings: ["spoon", "fork", "modem", "keychain"],
|
|
};
|
|
|
|
console.log(tralala.distro);
|

console.log(tralala.useWindows);

|
|
# Invalid binding names
|
|
|
|
Properties with invalid binding names or numbers must be quoted:
|
|
|
|
``` javascript
|
|
let weirdObject = {
|
|
tralala: "Chipmunk",
|
|
"this is a long binding name with spaces": "Fill in some nonsensse here"
|
|
}
|
|
|
|
console.log(weirdObject)
|
|
```
|
|
|
|
# Non existant property
|
|
|
|
Reading a non existant property returns `undefined`
|
|
|
|
``` javascript
|
|
let Object = {
|
|
thisExists: true,
|
|
};
|
|
|
|
console.log(Object.undefinedProperty); // undefined
|
|
```
