Still, your code is buggy and you don’t know why. You could read a 200-page book about how JavaScript works. But how much time do you really save if you keep making the same mistakes?Ī dry book won’t test your understanding. When there’s a fundamental gap in your understanding, it’s tempting to look the other way. Or, rather, you feel like you have to keep up. Now you have to keep up with all the new libraries and their updates, all the newsletters and tutorials, not to speak of all the problems you already encounter every day.

It was hard enough to learn programming from scratch. You need to see what happens as your program runs. But to gain confidence and find that bug, you need more than that. They read it according to the rules created by other humans decades ago. They don’t guess its meaning from variable names and familiar patterns. This is a difficult thing to admit to yourself! But it’s never too late to revisit.Ĭomputers don’t read code the way we do. You’ve learned to write code, but you haven’t learned how to read it. When you were learning programming, you focused on writing code. But lack of confidence often reveals a real knowledge gap. Why does it take you hours to fix a bug that others fix in a few minutes? I’m just trying different things hoping that one of them works. Soon, a voice in your head becomes impossible to ignore. Your confidence wanes with every attempt.

Should you remove this line? Reorder those two other lines? Maybe it will somehow just work if you try it again? Or did they? You’ve had to learn so much in so little time… The articles you’ve read and the tutorials you’ve watched did not prepare you for this moment. You read the code again and again, but you can’t spot the mistake. It strikes you in the middle of that interview. It strikes you during a pair coding session. It strikes you just as you were about to go home. Oh, what a marvellous illusion you have created! It works… With a few confident keystrokes, you breathe life into the colorful dots on the screen. You patiently enchant the machine with a tapestry of digital spells. On a good day, programming feels like magic.
