Description: A function reference is a fundamental concept in programming that allows treating functions as first-class objects. This means that functions can be assigned to variables, passed as arguments to other functions, and returned from other functions. In programming languages like TypeScript, which is a superset of JavaScript, function references are particularly useful for creating more modular and reusable code. When defining a function, a reference to it can be obtained simply by using its name, allowing it to be invoked in different contexts. This approach promotes functional programming, where functions are treated as first-class citizens, facilitating the creation of higher-order functions that can manipulate other functions. Function references are also key in implementing callbacks, promises, and event handling, making them an essential tool for developing interactive and asynchronous applications. In summary, function references are a cornerstone of modern programming, allowing for greater flexibility and expressiveness in code.
