When Julia is run without a program file as argument, the REPL (Read-Evaluate-Print Loop) runs. Entering a ? at the prompt brings up help, with help on a topic printer if the topic name is preceded by ? at the prompt.

Welcome to Julia 1.1.1. The full manual is available at
https://docs.julialang.org/
as well as many great tutorials and learning resources:

function
Functions are defined with the function keyword:
function add(a, b)
return a + b
end
Or the short form notation:
add(a, b) = a + b
The use of the return keyword is exactly the same as in other languages, but is often optional. A function without
an explicit return statement will return the last expression in the function body.
