I am trying to write a program to decrypt a encrypted message. The encrypted message is a very long set of numbers ".296.294.255.268.313.278.311.270.290.305.322.252.276.286.301.305.264.301.251.269.274.311.304.
230.280.264.327.301.301.265.287.285.306.265.282.319.235.262.278.249.239.284.237.249.289.250.
282.240.256.287.303.310.314.242.302.289.268.315.264.293.261.298.310.242.253.299.278.272.333.
272.295.306.276.317.286.250.272.272.274.282.308.262.285.326.321.285.270.270.241.283.305.319.
246.263.311.299.295.315.263.304.279.286.286.299.282.285.289.298.277.292.296.282.267.245.....ect". 
Each character of the message is transformed into three different numbers (eg.first character of message is '230 .280 .264' second character is '.327.301.265' ect).
so i am trying to use javascript to add the groups of three numbers and then save them as their own variable. thanks
