Mocha is a popular JavaScript testing framework that runs on Node.js and in the browser, designed to make asynchronous testing simple and fun. It provides a flexible structure for writing and organizing tests.


        
        // Import the assert module
        const assert = require('assert');

        // Describe a test suite
        describe('Array', function() {
            // Define a test case
            it('should return -1 when the value is not present', function() {
                assert.strictEqual([1, 2, 3].indexOf(4), -1);
            });
        });

ADDITIONAL COMMENT: - Mocha allows you to structure your tests using "describe" blocks for test suites and "it" blocks for individual test cases. - The "assert" module is used here for assertions, but you can use other assertion libraries like Chai. - To run tests, install Mocha globally with "npm install -g mocha" and execute "mocha" in your terminal. - Mocha supports both synchronous and asynchronous testing. ✅ Answered with JavaScript best practices.
