With this method, we can define anonymous function expressions in a short way. Example: var collection = (x, y) => x + y; document.write(collection(3,7)) Output:  10 Same as above example: var collection = function (x, y) { return x + y; }; document.write(collection(3,7)) As seen, the function expression is defined with a shorter method. The...

Recursion of the function.

As with most programming languages, JavaScript functions can call themselves. However, in this case, it is also necessary to establish a control mechanism that will finish the job of calling itself in one place. Otherwise, we receive a stack overflow error when the function calls itself too much. example: function write(dat) { if (dat >...
