This is my solution for a process review I took part in. Using TDD principles, I developed the required feature in a given time. I wrote my solution in JavaScript and used Jest to create my tests.
Mega soft weird: a company that develops a word processor
-
The feature that needs building today is a spell checker
-
It will accept a string of space seperated words and highlight words that have been mispelt. For example: "tme", ["time"] => "
tme" -
As a second parameter, it will accept the correctly spelt word in lower case.
| Input | Output |
|---|---|
| "time", ["time"] | "time" |
| "tme", ["time"] | " |
| "cta", ["cat"] | " |
| "Hand", ["hand"] | "Hand" |
| "haNd", ["hand"] | "haNd" |
| "the clock", ["the", "clock"] | "the clock" |
| "teh clock", ["the", "clock"] | " |
| "teh clokc", ["the", "clock"] | " |
| Edge Cases | |
| "" | Throw Error - "No words found." |
