Syntax Basics

Statements end with ;. Blocks use { }. Method calls chain with ..

name: str = "Echo";

if name == "Echo" {
    say(name.upperCase());
}

value: int = 10;
value = value + 1;

if value > 10 {
    say("big");
} else {
    say("small");
}

big

Notes

• Every normal statement ends with ;.
• if, while, for, foreach, and block-form fn use braces and do not take a trailing semicolon.
• Whitespace is mostly ignored outside tokens.
• Newlines improve readability; they are not syntax.
• Method chaining:

name: str = ask("Name: ").trim().upperCase();

Common Mistakes

Python-style bare blocks

while true
    say("loop");

Treating newlines as statement terminators

name: str = "Echo"
age: int = 1;

Treating . as field access

a.b is not OO property access. With (...) it is a method call.
