I was browsing the web and I noticed Ruby code that utilises a String
instance method called chars
.
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#chars
and 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.
Cheers for reading! 🤓
