Assigning a substitute value in case of nil
ruby
Solution
You could do this since a `nil` value returns false and `||` will only evaluate the right-hand side if the left-hand side is false:
name = personal_details[0] || ''
Problem
I have a few variables: ``` name age address phone social_security email weight ``` And an array called `personal_details` with each of these values in positions 0-6. So I assign values like this: ``` name = personal_details[0] address = personal_details[1] phone = personal_details[2] social_security = personal_details[3] email = personal_details[4] weight = personal_details[5] ``` In some cases, however, the data on the right hand side does not exist. What's a more elegant way to handle this than writing something like this for each element in the array? ``` if !personal_detail[0].nil? name = personal_details[0] else name = "" end if !personal_detail[1].nil? address = personal_details[1] else address = "" end ```
