Variables
Variables are named slots for storing values. You define a new variable in Zaidlang using the
= operator, like so:a = 1 + 2
This creates a new variable
a in the current scope and initializes it with the result of the expression following =. Once a variable has been defined, it can be accessed by name as you would expect.technology = "Micromachines"
printftw(technology) // >> Micromachines
Zaidlang has true block scope: a variable exists from the point where it is defined until the end of the block where that definition appears.
function foobar() {
printftw(a) // Error: "a" doesn't exist yet.
a = 123
printftw(a) // >> 123
}
printftw(a) // Error: "a" doesn't exist anymore.
Variables defined at the top level of a script are top-level, or global. All other variables are local. Declaring a variable in an inner scope with the same name as an outer one is called shadowing and is not an error.
a = "outer"
function foobar() {
a = "inner"
printftw(a) // inner
}
printftw(a) // outer
