The define form in Racket is used to name variables, functions, and constants.Racket's lambda creates anonymous functions without a name.Racket's if statement is a basic conditional form similar to standard if-else in Java, Python, and C#.The cond form in Racket is used for more than two branches and offers better readability than nested if statements.Racket's let form creates temporary bindings limited to a specific code block.Racket's let* form allows variables to refer to those defined before it.Racket's letrec form is used for defining mutually recursive functions.Quoting in Racket allows treating data as literal values rather than for evaluation.Racket's set! is used to change a variable's value after it's defined.Racket uses '#lang' at the top of files to specify the language module.The 'require' statement in Racket is used to import functions or data from another module.Racket supports keyword arguments for functions, making it easier to understand arguments.The match form in Racket allows unpacking and analyzing data using patterns.Racket's struct is used for defining custom data structures with constructors, accessors, and predicates.Racket allows declaring modules in the language to group and isolate code.Racket supports mutable structs by adding the #:mutable flag.Racket's define-values form returns the result of the first expression in a sequence.Racket has built-in support for returning multiple values from functions.Racket's syntax may feel unfamiliar initially, but understanding it leads to a natural flow.
