I was browsing the web and I noticed Ruby code that utilises a
String instance method called
Until today, I'd never used nor heard of
String#chars. What does it do?
String#chars is used to return an array of characters within a string.
name = 'Ali' name.chars => ["A", "l", "i"]
Do note that it does not work similarly to
String#split, although we can achieve the same result.
name = "Ali" name.split('') => ["A", "l", "i"]
So how are
String#split different to each other?
String#split uses a regular expression to divide characters within a string, thus returning an array.
String#chars parses the byte of each character within a string and then it returns an array.
