Prefixes vs. Suffixes

Create two functions: isPrefix(word, prefix-) and isSuffix(word, -suffix).

1. isPrefix should return true if it begins with the prefix argument.
2. isSuffix should return true if it ends with the suffix argument.

Otherwise return false.

Examples

isPrefix("automation", "auto-") ➞ true

isSuffix("arachnophobia", "-phobia") ➞ true

isPrefix("retrospect", "sub-") ➞ false

isSuffix("vocation", "-logy") ➞ false

Notes

The prefix and suffix arguments have dashes - in them.
