How can I add space character in the ruby array if I want to use %w(a b c) syntax?

%w(foo bar) is a shortcut for ["foo", "bar"] . Meaning it's a notation to write an array of strings separated by spaces instead of commas and without quotes around them. You can find a list of ways of writing literals in zenspider's quickref.
If you are using Rails, you can simply use: x. blank? This is safe to call when x is nil, and returns true if x is nil or all whitespace.
To check if a value is in the array, you can use the built-in include? method. The include? method returns true if the specified value is in the array and false if not.
split is a String class method in Ruby which is used to split the given string into an array of substrings based on a pattern specified. Here the pattern can be a Regular Expression or a string. If pattern is a Regular Expression or a string, str is divided where the pattern matches.
Escape it:
%w(a b\ c) # => ["a", "b c"] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
