Day of Days of Code: Exploring JavaScript&#s console.log()

Sun, August 11, 2024

Today, I delved into the JavaScript console.log() method, marking another milestone in my Codecademy development journey. So far, I’ve built a solid foundation in modern HTML and CSS, which are essential for web development. However, to create truly interactive online experiences, like those found in business services, we need to layer on additional technologies.

JavaScript is quite different from HTML and CSS that I've been studying in that it allows for dynamic interactions by enabling the creation, evaluation, and modification of variables and expressions, which can be applied to achieve more complex features, such as tracking online shipments by accessing third-party systems.

The console.log() method is a tool for developers that's built into all modern web browsers and is used to log messages and results, making it invaluable for testing and debugging. By entering values and verifying outputs, developers can ensure their code behaves as expected.

One of the standout features of JavaScript is its rich set of methods that can be applied to variables and expressions. For instance, the + operator can either add numbers, or combine (concatenate) strings (series of characters), depending on context. JavaScript also offers numerous methods for manipulating strings, such as changing case or removing whitespace.

Codecademy’s approach is both comprehensive and concise. We’re encouraged to use online references to familiarize ourselves with these methods, laying the groundwork for building more advanced web applications.
