Why won't this work?

18,126 PointsThe way you are calling Array.new is wrong. A function is called using (), however ruby allows you to omit them, BUT you must have a space in between the function name and parameters.
You can fix it in a number of ways, the easiest is just add a space between new and your array: (array=Array.new ["array"]
). Or you can do a shorthand version and write array = ["array"]
.
Reading the ruby docs is a very good place to read how to create objects and how to use methods

17,565 PointsBecause that's not a legal way of instantiating an array in Ruby.
You can either:
arr = Array.new
arr.push("One") or arr[0] = "One"
or simply do it in one line:
arr = ["One"]

28,888 PointsSara, you're on the write track with using brackets, but using them basically removes the need to specify Array.new
, they function as shorthand. So you can do:
array = ['array', 'another', 'yet another']
Another trick is to turn a list of words into an array using %w.
array2 = %w{array another another}
