Find the longest common prefix of multiple strings.

Describe the solution you'd like

declare function longestCommonPrefix(strs: ArrayLike<string>): string
assertEquals(longestCommonPrefix([]), '')
assertEquals(longestCommonPrefix(['']), '')
assertEquals(longestCommonPrefix(['flower', 'flow', 'flight']), 'fl')
assertEquals(longestCommonPrefix(['flower', 'glow', 'flight']), '')
assertEquals(longestCommonPrefix(['💩', '💫']), '')

Describe alternatives you've considered

Maybe an equivalent under collections for longest common prefixes of lists (array/ArrayLikes)?
