Code typing practice for programmers

Typing code is a different skill from typing prose, and practising prose does not improve it. English is about 99 percent lowercase letters on your strongest fingers. Code is brackets, quotes, underscores and symbols on your weakest ones, most needing Shift. Pick a language below and practise on real source rather than on passages.

Which programming language is hardest to type?

C++ is the hardest and SQL is the easiest, and the reason is the proportion of characters that need Shift. The speeds below are what to expect relative to your prose speed once the language is familiar.

Typing difficulty by programming language
LanguageHardest keyWhy
Python:Ends almost every block. The single most typed symbol in Python.
JavaScript{Objects, blocks and destructuring. The most typed bracket in the language.
Java<>Generics. Almost always a matched pair, sometimes nested.
C*Pointers and dereferencing. Adjacent to the ampersand, which is the problem.
C++::The weakest finger typing the same shifted key in succession.
SQLShiftHeld across whole keywords, not tapped. The defining difficulty of SQL.

How to practise typing code

  1. Type complete snippets, not isolated symbols. The difficulty in code is the transition between characters — a colon is easy alone and hard after a closing bracket.
  2. Turn autocomplete off while practising. Your editor closes brackets for you, which means the closing runs are the part you have never actually typed.
  3. Do not correct as you go. Type the snippet through, then look at where the errors clustered. They cluster, and where they cluster is the answer.
  4. Practise the language you are paid to write. Symbol habits transfer only partly: Python fluency does nothing for C++ angle brackets.
  5. Fix the indentation, not just the characters. In Python it is syntax; everywhere else it is what makes the diff readable.

Learn the symbol keys properly first

If you are hunting for braces rather than merely slow at them, the symbol guides cover one character each — where it is, which finger owns it, and how to reach it without leaving the home row. The course also ends with a module of nothing but code.

Questions about typing code

What is code typing practice?

Practice using real source code instead of prose. It matters because the two have almost nothing in common as typing: ordinary English is about 99 percent lowercase letters typed by the strongest fingers, while code is dense in brackets, quotes, underscores and symbols typed by the weakest ones, most of them needing Shift.

Why am I slow at typing code but fast at typing text?

Because the keys are different, not because you type badly. Years of typing prose have made the letters automatic and left the symbol row almost untouched, since a full stop and the occasional comma is all ordinary writing asks for. Code asks for braces, angle brackets and underscores constantly, and none of them have ever had the chance to become automatic.

Which programming language is hardest to type?

C++, because it has the highest density of shifted symbols. A single declaration can contain double colons, angle brackets and ampersands within a dozen characters, all of them needing Shift and most of them landing on the right little finger. SQL is the easiest of the common languages, because it is mostly words rather than punctuation.

Does typing speed actually matter for programmers?

Less than for data entry, and more than programmers usually admit. Typing is rarely the bottleneck in solving a problem, but hunting for a brace interrupts the thought you were holding while you wrote the line, and that interruption is the real cost rather than the seconds themselves.

Should I practise with autocomplete turned off?

For practice, yes. Editors close your brackets for you, which means the closing runs are the part you have never actually typed, and that is exactly where people fall apart in a terminal, a code review box or an interview. The exercises here have no autocomplete for that reason.
