Variables

Variables can be declared using batarang

batarang x = 43
batarang y = 68
batarang z = 23

x = x + 1
y = 33
z = ((x + y) * (x + z)) / 34

Types

Numbers, strings and boolean are like other languages. Null value can denoted using mystery. String values can be only defined with " (double quotes)

batarang x = 43
batarang y = 12.34
batarang z = "dark knight"
batarang a = mystery
batarang b = True
batarang c = False

Input/Output

Use batSignal() to print anything to console and use batDirective() to take number or string as input. You can't take input in the web playground!

batSignal("I am Batman")

batarang a = 34
batSignal(a)

prompt = batDirective()
batSignal(prompt)

Conditionals

batIf defines a if statement, batElif defines a else if statement, batElse defines a else statement.

batarang a = 30

batIf a > 20 {
    batSignal("a is greater than 20")
}
batElif a > 15 {
    batSignal("a is greater than 15")
}
batElse {
    batSignal("a is greater than 10")
}

Loops

Statements inside fight till blocks are executed as long as specified condition evaluates to True. If the condition becomes False, statement withing the loop stops executing and control passes to the statement following the loop. The break and continue keywords have not been implemented yet.

batarang a = 5

fight till a > 0 {
    batSignal(a)
    a = a - 1
}

Functions

A function can be defined with the keyword batCave and function name. return can be used inside the function.

batCave add(a, b)
{
    return a + b
}

batarang z = add(10, 5)
batSignal(z)

Array

An array can be created with the keyword utilityBelt and array name.

utilityBelt arr = [1, 2, 3, 4, 5]
batSignal(arr)

batarang i = arr[0]
batSignal(i)
