How do you define a function in CoffeeScript?
Functions in CoffeeScript In CoffeeScript, we define only function expressions. The function keyword is eliminated in CoffeeScript. To define a function here, we have to use a thin arrow (->). Behind the scenes, the CoffeeScript compiler converts the arrow in to the function definition in JavaScript as shown below.
What are named functions?
A named function has 4 basic parts: the function keyword, the name you give it and use to refer to it, the parameter list, and the body of the function. Named functions can also be assigned to attributes on objects, and then you can call the function on the object: function sayHi() { console.
Do anonymous functions get hoisted?
Anonymous functions, on the other hand, are not hoisted. As you can see, when we call the “brag” function before the function declaration, we get an error. When we call it after the declaration, it works.
How do you call a function named myFunction?
Define a function named “myFunction”, and make it display “Hello World!” in the
element. Hint: Use the function keyword to define the function (followed by a name, followed by parentheses). Place the code you want executed by the function, inside curly brackets. Then, call the function.
Is CoffeeScript obsolete?

Why do you need a function in CoffeeScript?
CoffeeScript – Functions. A function is a block of reusable code that can be called anywhere in your program. This eliminates the need of writing the same code again and again. It helps programmers in writing modular codes.
Can you assign default values to function arguments in CoffeeScript?
CoffeeScript supports default arguments too. We can assign default values to the arguments of a function, as shown in the following example. On compiling, the above CoffeeScript generates the following JavaScript file. On executing the above CoffeeScript code, it generates the following output.
What are two types of functions in JavaScript?
In general, using JavaScript, we can define two types of functions – named functions, the regular functions with function name body and, Function expressions. Using function expressions, we can assign functions to variables. The syntax of function in CoffeeScript is simpler as compared to JavaScript.
