Read MoreLength of longest string chain in JavaScript
Word ChainLet's say word1 is a predecessor of word2 if and only if we can add exactly one letter anywhere in word1 to make it equal to word2. For example, "abc" is a predecessor of "abac".A word chain is a sequence of words [word_1, word_2, ..., word_k] with k >= 1, where word_1 is a predecessor of word_2, word_2 is a predecessor of word_3, and so on.ProblemWe are required to write a JavaScript function that takes in an array of strings, arr, as the first and the only argument.Each string in the array arr consists of English lowercase letters.
