In JSONATA, how to fetch values from object using variable

Question

$test := 'Account Name';

I need to know how can I use the variable as a key. These are not working:

1. $.$test
2. $.[$test]
3. $[$test]

Answer 1

You can use $lookup function to access a dynamically defined key:

$lookup($, $test)
