Javascript Programming Tutorials, Guides & Best Practices

The Revealing Module Pattern is a variation of the Module Pattern. It allows you to define all functions and variables in the private scope, and then selectively reveal those you want to be public.

const RevealingModule = (function() {
    let privateVariable = 'I am private';

    function privateFunction() {
        console.log(privateVariable);
    }

    function publicFunction() {
        privateFunction();
    }

    // Reveal public pointers to private functions and properties
    return {
        publicFunction: publicFunction
    };
})();

RevealingModule.publicFunction(); // Output: I am private
