Calling Function is the Essence of Coding WolframLang
- There are about 7 thousand function builtin. (6979 Symbols as of version 12.2)
- No need to load/import library to use builtin functions. Just call them directly.
Coding in WolframLang is essentially just about calling functions, nothing else.
There is no “statements”.
Everything is an expression.
You change the expression by calling a function on it and get the return value.
Even the typical assignment such as x = 3, is actally calling a function (Set[x,3]).
Any function returns a value. For example, Set[x,3] returns 3.
Any software written in WolframLang, the entire source code, is one nested sequence of function calls.
It's essential to be able to find the function you want.
All WolframLang's function names are long and descriptive.
