Default value needed if key not exist inside some object in array of objects about jmespath.js

[darrenmothersele]

Explanation:

The & denotes an expression is to be used as a value, rather than it being evaluated.

The map function takes an expression and an array as arguments. It applies the expression to each item in the array and returns an array of the results.

And `` denotes an empty string. The expression name || `` means that if the value for name is null then the empty string is used instead.

Does this help?

map(&(name || ``), @)
