It was Linux file permissions that made me think "oh, cool I can use a single number to represent multiple states." The irony is that I was just using integers as bits and writing switch statements rather than using bitwise operators! I'm attempting to rebuild that code to actually learn and incorporate those operators. #### Integer to binary conversion \`\`\`(5).toString(2) //'101' \`\`\` #### Binary to integer conversion
