Helloworld Project#

Create a main.move file in the sources folder:

module Lesson1::HelloWorld{
    use std::debug::print;
    use std::string::utf8; //Move doesn't support String type, you need to introduce string.

    #[test]
    fun test_hello_world(){
        print(&utf8(b"Hello World")); //
        /*
        1. Strings are not recognized and need to be preceded by a b, meaning converted to bytes.
        2. & var, for read-only, & mut var, for readable and writable
        */
    }
}

Important notes have been written in the comments, even Chinese characters cannot be written in the comments, otherwise compilation errors will occur.

Save the code and compile it with aptos init

Run it with aptos move test

The console will output Hello World
