Each of these values can usually be stored in a variable, either by [[assignment]] or [[function definition]]. Values of these types can also be written directly in many cases, with [[string]]s, [[numeric literal]]s, or [[array notation]], as predefined [[primitive]] | Each of these values can usually be stored in a variable, either by [[assignment]] or [[function definition]]. Values of these types can also be written directly in many cases, with [[string]]s, [[numeric literal]]s, or [[array notation]], as predefined [[primitive function]]s and [[primitive operator|operators]], or as inline [[dfn]]s. There are some anomalies which do not fit easily into this system, such as [[Outer Product]], which is written with two [[glyph]]s, and [[function-operator overloading]]. | ||
