Previous Question Next Question

Babel is a JavaScript compiler that allows developers to use modern JavaScript features by transforming them into a version that is compatible with older environments. This ensures that your code can run in various browsers and environments that may not support the latest JavaScript standards.

<!-- BEGIN COPY / PASTE -->
        // Example of Babel transforming modern ES6+ code to ES5

        // Original ES6+ code
        const greet = (name = "World") => `Hello, ${name}!`;

        // Transformed ES5 code by Babel
        var greet = function(name) {
            if (name === void 0) {
                name = "World";
            }
            return "Hello, " + name + "!";
        };
        <!-- END COPY / PASTE -->

Additional Comment:

Babel is often used in conjunction with build tools like Webpack or Gulp.
It allows developers to write code using the latest JavaScript syntax and features.
Babel plugins and presets can be configured to control which features are transformed.
Babel can also polyfill newer JavaScript features that are not natively supported in older environments.
