​Working with Variables

📥 Inputs

WayScript's JS editor lets you reference Variables that exist in your program. To do this, you can reference them through the variables dictionary.

As an example, let's create a variable called "Location" and set a value of "Brooklyn, NY"

You can reference the Location variable in your JavaScript with this code:

location = variables[ "Location" ];
​
// Or, as a JS object
location = variables.Location;

More abstractly, you reference any variable with the format:

const my_var = variables[ "<var_name>" ];

​📤 Outputs

​ Return Data from Your JavaScript

You can also output data from your JS code and turn these into variables that can be used by other Modules in your program.

You can do this with the variables dictionary in the following format:

variables[ "<Var Name>" ] = variable;
​
// example
const currentTime = new Date();
variables[ "Date" ] = currentTime.toISOString();

​🖨 Output Raw JavaScript Code

You can output the raw JavaScript code from the code editor by enabling the "JavaScript Code" output. This is useful when building a website using WayScript and inserting JavaScript into HTML.

​▶ Running JavaScript

While working on your code, you can press the "Run Code" button inside the module to run the JavaScript and see updated results.

​📦 Adding Dependencies

If you would like to use an npm module in your code, you can declare those dependencies in the "Requirements.txt" file.

Declare these dependencies on separate lines, using the format you would for an npm-install command.

You can then consume these packages in your code:

const wayscript = require( 'wayscript' );
​
wayscript.apiKey = 'YOUR_API_KEY';
​
let programId = 1234;
wayscript.runProgram( programId );

​↘ Importing Code from Other Files

You can import code from the other JavaScript files in your File Browser. For example, suppose you have a file called foo.js, which has an exported function bar.

You can import and use the bar method in scratch.js by using a relative import:

const foo = require('./foo');
