Using Use in Gleam

Erika Rowland, also known as erikareads, discusses the use of the "use" expression in Gleam programming language. The "use" expression was introduced in Gleam v0.25 as a replacement for the "try" keyword. It allows for a more concise and clear way of writing functions that involve callback functions as their last argument. By using "use," the code structure becomes more streamlined, especially in error handling and context management scenarios. The article provides examples of how "use" can simplify code by avoiding nested callback functions and improving readability. While "use" is considered syntax sugar and not essential, it can enhance code clarity by focusing on the main logic of the program. The choice of "use" as a keyword was a result of discussions within the Gleam community to introduce a general syntax sugar. Overall, the use of "use" in Gleam can help developers emphasize the main flow of their code while addressing error handling and context management concerns effectively.
