Learning Julia

Creating functions

Functions in Julia are declared with the function keyword, which is then followed by the body of the function. Another keyword, end, puts or marks a logical end to the function in general. The syntax of defining a function can be summarized as:

function name()        …   body      …end

The function's name has to be followed by a bracket (). Failing to do so will result in an error. People coming from languages such as Python may find it a little different, but it becomes easy as you start coding in Julia. Let's just have a look at how a function is defined and used inside Julia's REPL:

julia> function greet()           println("hello world")       endgreet (generic function with 1 method)julia> greet()hello world
