Lodash matches nested. matches() supports deep comparison of nested objects.
Lodash matches nested. I have a complex data structure, with nested arrays and I need to find an element with a string value using a case insensitive search. matches, or _. Hi, maybe I misunderstand the doc. Without a library, you could directly use Array#filter to obtain only specific elements.
