# Type Functions

Built-in functions for inspecting and creating values by type. They are always available - no import required.

* `typeof(value)` returns the name of a value's type as a string.
* `symbol()` creates a unique symbol value.

For converting a value from one type to another (`.toStr()`, `.toNum()`, `.toInt()`, `.toBool()`), see the [type methods](/methods/types.md).
