When should you use curly brackets?

Curly brackets, or braces {}, are typically used in programming languages to define blocks of code, such as functions, loops, or conditionals. They help group statements together, indicating that they should be executed as a unit. Additionally, in some contexts like JSON data formatting, curly brackets are used to denote objects or key-value pairs. Always refer to the specific syntax rules of the programming language or framework you are using for proper usage.
