Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | // NB COPYPASTE! |
||
| 2 | console.log(JSON.stringify(main(), null, 2)) |
||
| 3 | |||
| 4 | function main() { |
||
| 5 | const {env} = process |
||
| 6 | , collected = {} |
||
| 7 | , keys = [] |
||
| 8 | |||
| 9 | for (const key in env) { |
||
| 10 | if (!key.includes("SPEC_")) |
||
| 11 | continue |
||
| 12 | |||
| 13 | collected[key] = env[key] |
||
| 14 | keys.push(key) |
||
| 15 | } |
||
| 16 | |||
| 17 | const {length} = keys.sort() |
||
| 18 | , $return = {} |
||
| 19 | |||
| 20 | for (let i = 0; i < length; i++) { |
||
| 21 | const key = keys[i] |
||
| 22 | $return[key] = collected[key] |
||
| 23 | } |
||
| 24 | |||
| 25 | return $return |
||
| 26 | } |
