A Day in the Life
What your typical workday looks like
Imagine starting your day by checking your code from yesterday and planning what new features to build. You might spend your morning collaborating with designers to understand how a new part of a website should look and behave, then dive into coding, writing instructions in JavaScript to make buttons clickable, forms submit data, and content update without reloading the page. In the afternoon, you might work with other developers to test your code, fix any bugs that pop up, and get feedback to make the user experience even better. It’s a mix of creative thinking, detailed problem-solving, and teamwork.
