Required version: Sponge >=1.0.0

Variables and Declarations

Let Binding

Declare immutable variables with let:

let name = "Sponge";
let age = 5;
let pi = 3.14159;
let is_fun = true;

Variable Assignment

Update variable values:

let x = 10;
x = 20;  # assignment

Compound Assignment

Shorthand operators for common operations:

let count = 5;
count += 3;   # count = count + 3
count -= 1;   # count = count - 1
count *= 2;   # count = count * 2
count /= 4;   # count = count / 4

Data Types

Sponge supports several built-in types:

Type	Example	Description
Number	`42`	Integer values
Float	`3.14`	Floating-point numbers
String	`"hello"`	Text data
Boolean	`true`, `false`	Logical values
Array	`[1, 2, 3]`	Ordered collections
Dictionary	`{a: 1, b: 2}`	Key-value mappings
Null	`null`	Absence of value

Operators

Arithmetic

let a = 10 + 5;      # 15
let b = 10 - 3;      # 7
let c = 4 * 5;       # 20
let d = 20 / 4;      # 5
let e = 17 % 5;      # 2
let f = 2 ** 3;      # 8 (power)

Comparison

let eq = 5 == 5;     # true
let neq = 5 != 3;    # true
let lt = 3 < 5;      # true
let gt = 5 > 3;      # true
let lte = 5 <= 5;    # true
let gte = 5 >= 3;    # true

Logical

let a = true and false;   # false
let b = true or false;    # true
let c = not true;         # false

String Operations

String Concatenation

let greeting = "Hello" + " " + "World";
print(greeting);  # Hello World

String Functions

let text = "Sponge";
print(len(text));           # 6
print(upper(text));         # SPONGE
print(lower(text));         # sponge
print(slice(text, 0, 4));   # Spon
print(contains(text, "onge"));  # true

String Splitting

let parts = split("a,b,c", ",");
print(parts);  # [a, b, c]

Comments

# Single-line comment

/* Multi-line
   comment */
