Description: A function literal is an expression that defines a function without a name, also known as an anonymous function. This type of function is commonly used in programming to create functions that can be passed as arguments to other functions, assigned to variables, or executed immediately. Function literals are a fundamental feature in programming languages like JavaScript and TypeScript, allowing for greater flexibility and modularity in code. Since they do not have a name, these functions are ideal for situations where a temporary or one-time-use function is needed, such as in callbacks or when creating higher-order functions. Additionally, function literals can capture the context in which they are defined, allowing access to variables from the outer scope, a concept known as ‘closure’. This ability to encapsulate state and behavior in an anonymous function is one of the reasons why function literals are so popular in modern programming across various programming languages, facilitating the writing of cleaner and more maintainable code.
