5. Hello World Method

For this tutorial, we are going to write a method and returns "Hello, NAME" with NAME being an argument to the method.

Modifying the Contract

import { Contract } from "@algorandfoundation/tealscript";

// eslint-disable-next-line no-unused-vars
class HelloWorld extends Contract {
  /**
   * @param name The name of the caller
   *
   * @returns A greeting string
   */
  hello(name: string): string {
    return "Hello, " + name;
  }
}

Compile New Contract

To compile the contract, run npm run build. This should update all of the files in contracts/artifacts and contracts/clients

Template Literals

It should be noted that TEALScript does not currently support string literals. For example, the following syntax is not yet supported:

return `Hello, ${name}`
