Functions

Functions are the core building blocks of a Fluency Programming Language script.

• Each script must have a main function.
• Allows custom, user defined functions
• Many core functions / features are provided by built-in functions

Functions have must return some value

function <name> (parameters) { }

Custom functions

As a programming language, FPL allows arbitrary, user defined functions.

function main() {
    let s = 100
    return customFunction(s)
}

function customFunction(s) {
    if (s > 100) {
        printf("s is greater than 100")
    } else {
        printf("s is less than or greater to 100")
    }
    return {}
}

Built-in Functions

Many functions are provided by built-in functions. See the link (section) for a full listing of built-in functions.
