Speed Typing Games for Programmers

How this list was compiled: Five sets of words chosen for a falling-words typing game and checked on 2026-10-09 against the public reference each word comes from; every word is written in lower-case letters only, with 2 to 10 letters, and no word is used twice. Levels 1 and 2 (control flow and declarations) are reserved words and words with a special meaning from the keyword lists of four languages: MDN Web Docs, JavaScript reference, Lexical grammar (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Lexical_grammar); The Python Language Reference, section 2.3.1 Keywords and 2.3.2 Soft Keywords (https://docs.python.org/3/reference/lexical_analysis.html); The Go Programming Language Specification, Keywords (https://go.dev/ref/spec); The Rust Reference, Keywords (https://doc.rust-lang.org/reference/keywords.html). Level 3 (types and values) adds the predeclared identifiers of the Go specification and the built-in types listed in The Python Standard Library, Built-in Functions (https://docs.python.org/3/library/functions.html). Level 4 (shell commands) is taken from the utilities index of The Open Group Base Specifications Issue 7, 2018 edition, which is the POSIX standard (https://pubs.opengroup.org/onlinepubs/9699919799/idx/utilities.html). Level 5 (version control) is taken from the command list of the Git reference manual (https://git-scm.com/docs). All seven pages were read on 2026-10-09. The sorting of the words into levels is this page's own. No language, product or company name is a word of any level, and a word with a symbol, a digit or a hyphen in it is left out. Licence: own work (a selection of single reserved words and command names from the public references named in the source; single words are not works)
