This question explores JavaScript and addresses practical considerations related to: How do I ensure browser compatibility with JavaScript code?

Ensuring browser compatibility in JavaScript involves using features supported by all target browsers or using tools to transpile modern code to an older syntax. Here's a simple example using Babel to transpile ES6+ code to ES5 for broader compatibility. // Original ES6+ code const greet = (name) => `Hello, ${name}!`; // Transpiled ES5 code using Babel var greet = function(name) { return "Hello, " + name + "!"; }; ADDITIONAL COMMENT: - Use Babel to transpile modern JavaScript (ES6+) to ES5, which is widely supported by older browsers. - Set up Babel in your development environment to automatically transpile your code. - Consider using polyfills for features not natively supported in older browsers. - Regularly test your code in different browsers to ensure compatibility. ✅

<!-- BEGIN COPY / PASTE -->
        // Original ES6+ code
        const greet = (name) => `Hello, ${name}!`;

        // Transpiled ES5 code using Babel
        var greet = function(name) {
            return "Hello, " + name + "!";
        };
        <!-- END COPY / PASTE -->
