How to write programs for nix.js

• You should have only one user-facing function, with all helper functions scope restricted.

  • Your primary function should be declared like: function myFunction(args)
  • Any helper functions should be scope restricted, using const: const myHelper = function()

• Your primary function should be the title of your program (hello.js should have a public hello function).

• Your primary function will receive an array of arguments that the user gives to it.

  • For example, $echo hello there results in args === ["hello", "there"] in the echo(args) function call.

Functions you should use:

addLine(text)

• Where text is the text you want printed to a new line.
• Returns the index of the line you just created.

changeLine(index, text)

• Where index is the index of the line you want to change.
• And text is the text you want the line to be changed to.
• Note that you have unlimited access with this function, and can end up changing lines you didn't indend to if you aren't careful.

Example of a well-written program:

function helloNameAndDate(args) {
   if (!args[0]) {
       addLine("Please provide a name.");
       return;
   }
   const name = args[0];
   const date = getDate();
   addLine(`Hello, ${name}. It is: ${date}`);
}

const getDate = function() {
    const clock = new Date();
    return `${clock.toDateString()}, ${clock.toTimeString()}`;
};
