    Parameters

    A parameter as a name, and can be optionally contained inside brackets.

    2 + x, 2 + [x]
    Function

    A function is made of a name followed by braces, containing optionally any value as arguments. Abs(1), doSomehting(1, 'dummy')
    Operators Expressions can be combined using operators. Each operator as a precedence priority. Here is the list of those expression's priority.
    1. primary
    2. unary
    3. power
    4. multiplicative
    5. additive
    6. relational
    7. logical
    Logical These operators can do some logical comparison between other expressions:
    • or - ||
    • and - &&
    • true or false

    The and operator has a higher priority than the or, thus in the example above, false and true are evaluated first.
    Relational Relational operators are used to compare values. These operators always result in a boolean value.
    • =, ==, !=, <>
    • <, <=, >, >=
    • 1 < 2
