The terms “such as†and “like†are two different terms that are different in meanings but can as well have similar meanings a few times. The word “like†can actually be versatile in its usage and can be used in almost all parts of speech. "Like" can be used in a sentence as a noun, verb, adjective, adverb, conjunction, preposition, and interjection. On the contrary, “such as†is more or less an idiomatic expression, which basically takes preposition as its part of speech in sentences. The term “such as†can mean “for example,†“for instance,†“like†(usually in its adjectival form), and other similar meanings. Hence, you can use “like†to describe things with similar qualities, degrees, or quantities. “Like†can just be used with any kind of item, which might be indefinite, while “such as†is used when the items are more precise and specific.
