0:00:04.000,0:00:08.720 this exercise asks us how we would 0:00:06.160,0:00:11.440 access the name of the person 0:00:08.720,0:00:12.240 we've got a hash here on line one and we 0:00:11.440,0:00:14.920 want to 0:00:12.240,0:00:16.320 access the value associated with the 0:00:14.920,0:00:18.240 name 0:00:16.320,0:00:20.800 in order to do that we can use element 0:00:18.240,0:00:20.800 reference 0:00:22.480,0:00:25.680 so in these square brackets we're going 0:00:24.240,0:00:28.800 to place the key 0:00:25.680,0:00:30.960 which in this case is a symbol 0:00:28.800,0:00:32.719 in this case we want to access the value 0:00:30.960,0:00:36.239 associated with the name 0:00:32.719,0:00:38.239 key passing in the key here is going to 0:00:36.239,0:00:38.879 return the value associated with that 0:00:38.239,0:00:40.719 key 0:00:38.879,0:00:42.320 so in this case it will be the string 0:00:40.719,0:00:46.239 bob 0:00:42.320,0:00:46.239 let's use p to output this 0:00:48.640,0:01:00.000 and we see bob you
