This auto-boxing behavior is not observable in JavaScript code but is a good mental model of various behaviors - for example, why "mutating" primitives does not work (because str.foo = 1 is not assigning to the property foo of str itself, but to an ephemeral wrapper object). For example, "foo".includes("f") implicitly creates a String wrapper object and calls () on that object. When properties are accessed on primitives, JavaScript auto-boxes the value into a wrapper object and accesses the property on that object instead. Primitives have no methods but still behave as if they do. The language does not offer utilities to mutate primitive values. The variable may be reassigned to a new value, but the existing value can not be changed in the ways that objects, arrays, and functions can be altered. It is important not to confuse a primitive itself with a variable assigned a primitive value. Most of the time, a primitive value is represented directly at the lowest level of the language implementation.Īll primitives are immutable that is, they cannot be altered.
