Programming has changed over the past 20 years. This is because programming has never been easier, with new languages, and tools you can use to help build anything with a simpler learning curve compared to 20 years ago.
Now you can use tools, like Astro, Vue.js, React and more to build websites with ease where in the past you would have had to use HTML, JavaScript, and CSS.
The security standards of websites have also changed, meaning that both you (the developer) and the user will have a safer experience on the internet.
