I'm still fairly new to programming, and I have days where I make lots of simple mistakes: typos, missing semicolons, mistyped method names, and similar errors. Even when I reread my code, I sometimes don't notice what's wrong. For example, while writing a C# test for ToString(), I accidentally returned the implementation instead of using Assert.Equal(...). It's starting to frustrate me. Does this improve mainly through practice and repetition, or are there better habits and tools I should use?

Formatters, linters, compiler warnings, and tests can remove a lot of mental overhead. Configure your editor to format code automatically and highlight suspicious patterns. For the mistakes that compile successfully but produce the wrong result, small focused tests and reviewing the behavior—not just whether the program runs—are especially useful.
Think of writing code like writing a first draft. In the first pass, focus on getting the idea implemented. In the second pass, use formatting, compiler feedback, tests, and a careful review to clean up names, syntax, and logic. Separating those two stages is often easier than trying to write perfect code immediately.
It’s completely normal, even for experienced developers. Everyone has distracted or tired days when they overlook something they’ve done hundreds of times. The goal isn’t to eliminate every mistake; it’s to build a workflow that catches mistakes quickly and makes them easy to fix.
Yes, repetition helps, but these mistakes never disappear completely. Use the tools available to you: IntelliSense can catch many naming errors, and the compiler will point out syntax problems such as missing semicolons. Over time, you’ll also become more familiar with the code and notice when something looks wrong.
That makes sense. The editor and compiler catch the basic problems, while the harder part is becoming familiar enough with the code to recognize when something feels off.
