MOTOKO — THE NATIVE LANGUAGE OF ICP

Motoko is the programming language designed specifically for writing ICP canisters.

WHY MOTOKO:

1. Purpose-built for ICP

2. Native support for canister features

3. Strong type system

4. Easy to learn for JavaScript developers

5. First-class support for actors and messages

BASIC SYNTAX:

actor Hello {

public query func greet(name: Text) : async Text {

return "Hello, " # name # "!";

};

};

KEY CONCEPTS:

1. Actors

Canisters are actors. They communicate via messages. Each actor has its own state.

2. Asynchronous Execution

All inter-canister calls are asynchronous. No blocking.

3. Pattern Matching

Powerful pattern matching for data types. Similar to Rust or Haskell.

4. Stability

The stable keyword preserves state across upgrades.

5. Modules

Code is organized into modules. Import and export functionality cleanly.

MOTOKO vs RUST:

Motoko is easier to learn. Rust is faster and more flexible. Choose Motoko for rapid development. Choose Rust for performance-critical applications.

MOTOKO ECOSYSTEM:

- Vessel: Package manager

- moc: Compiler

- dfx: Build tool

- Motoko Playground: Online IDE

This is where most ICP developers start. Simple, clean, and powerful.
