The toString() method is very simple. You can call it on anything, and if nothing has been defined, it'll use the default version. Many objects, like arrays, do define their own version. Custom objects can also define a version. When you interpolate an object into a string literal- console.log("This is my object: " + myObject)-it will call the toString() method.
JavaScript is the layer of the web that turns static pages into interactive experiences. While HTML structures content and CSS controls presentation, JavaScript responds to user actions, updates content dynamically, and connects logic to what happens in the browser. For many beginners, JavaScript is also where learning starts to feel less abstract. You write code, refresh the page, and immediately see something change. This direct feedback helps explain not just how JavaScript works, but why it matters. Many learners first encounter JavaScript through online coding courses, where short exercises make it easier to experiment and understand how code affects real pages.
Dear JS ecosystem, I love you, but you have a dependency management problem when it comes to the Web, and the time has come for an intervention. No, this is not another rant about npm's security issues. Abstraction is the cornerstone of modern software engineering. Reusing logic and building higher-level solutions from lower-level building blocks is what makes all the technological wonders around us possible. Imagine if every time anyone wrote a calculator they also had to reinvent floating-point arithmetic and string encoding!
