Because the randomNumber supposed to generate a value of the index, and the length is always 1 higher than the index, which would result in the result in the value of undefined. Therefore the -1 is needed. ]]> 2021-01-11 18:09:31 UTC https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075442271 dhillonstaples5139 https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075442409 QUESTION 2:
If this line read (0,nounList.length), the code would choose an index that may be null (which is 11, as the length of the list is 11 strings long, but the index values are between 0-10,) meaning the display would read 'undefined.' We, obviously, do not want this, so we would add the '-1' to the end of the line.]]> 2021-01-11 18:09:32 UTC https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075442409 jasminmendietaarana1900 https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075443618 With the -1 it would say which number is used last in the list.]]> 2021-01-11 18:09:44 UTC https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075443618 rarofx https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075445230 What would break if this line read randomNumber(0,nounList.length) instead of randomNumber(0,nounList.length-1)?]]> 2021-01-11 18:10:01 UTC https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075445230 samad_ahmed4672 https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075446092 The Length of a list is always +1 larger than the max index, since the index numbers start counting from index 0, meaning that if there wasn't a -1 the index variable could potentially be assigned an index that doesn't exist, which would break the program.]]> 2021-01-11 18:10:10 UTC https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075446092 daniela_acevedomoran4673 https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075446921 Without the -1 the code would be undefined]]> 2021-01-11 18:10:19 UTC https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075446921 anhdo0417 https://padlet.com/rarofx/8yphjmrkcqmf32mf/wish/1075447214 "noun.Length" is the total item/index, but "noun.length-1" will give the index of the element.
