Ruby Ruby Objects and Classes Build a Bank Account Class Adding Transactions

why is the ":" sign at the end rather the begining of a symbol> isnt the right syntax :symbol rather than symbol:

when pushing hash into the array

bank_account.rb
class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
  end
def add_transaction(description, amount)
    @transactions.push(:description description, :amount amount)
  end
end

In Ruby's Hash literal.

{description: description, amount: amount}
# is just a shorthand of writing the following line
{:description => description, :amount => amount}

the narattor skipped that one,,,{!!!}

Really? Jason did?

But anyway, yeah, since when writing Ruby code, you'll write a lot of Hash, so Ruby just give you a shorthand, more concise way of writing it.

ive done all the hash tutorial, and tis syntax never appears. Jason simply used it without explaing this secret trick...:\
