The omitEmpty Function

This article discusses the omitEmpty utility function from the @splendidlabz/utils package. The author explains how to handle conditional object properties in JavaScript, comparing direct assignment and conditional spread methods, then introduces omitEmpty as a cleaner alternative. The function recursively removes keys with empty values (null, undefined, empty string, empty object, empty array) and supports a shallow option to prevent deep recursion. The article includes usage examples and links to the package.
