The phrase "What type of" can refer to different contexts depending on usage:

• In language and grammar, "what type of" and "what kind of" are often interchangeable with subtle differences. "Type" is slightly more formal and used to distinguish specific characteristics or categories, while "kind" associates an individual with a group. For example, "type" is preferred when referring to distinct traits within a group, whereas "kind" is more common in everyday speech

• In popular culture, "What Type of X" is the title of a 2021 digital single by the Korean-American artist Jessi. The song and its music video have been released on platforms like YouTube, Apple Music, and Spotify

• In programming, specifically JavaScript, the typeof operator is used to determine the data type of a variable or expression. It returns types such as "string," "number," "boolean," "object," and "function," among others. This operator helps identify primitive types and complex data types like objects and functions

Thus, "what type of" can be a grammatical phrase, a song title, or a programming operator depending on context.
