# Mutable
The difference between objects and primitive values is that **we can change objects**, whereas primitive values are immutable.
~~~
var myPrimitive = "first value";
myPrimitive = "another value";
// myPrimitive now points to another string.
var myObject = { key: "first value"};
myObject.key = "another value";
// myObject points to the same object.
