What is a Snippet?
A small section of text or source code that can be inserted into the code of a program or Web Page is called a Snippet. Snippets help solve the problem of rewriting commonly used code or functions. A web developer or programmer can save the code or function as a Snippet and can drag or drop the Snippet wherever it is needed. Snippets help in organizing common code sections into categories.
