How would you implement method overloading in JavaScript without using classes?
Method over loading is a technique in which a function or method can have multiple definitions that vary by the number and / or types of arguments passed to it . This technique is commonly used in object - oriented programming languages such as Java , C # and C ++ , but is not available in languages such as JavaScript . However , it is possible to implement method over loading in JavaScript without using classes . The most common approach is to use function parameters and argument checking . Function parameters are the parameters that are declared when the function is defined . They can be used to check the number and types of the arguments that are passed to the function . For example , the following function is defined with two parameters : function sum ( a , b ) { return a + b ; } The parameters “ a ” and “ b ” indicate that the functio...
