How can implement overloading in JavaScript/jQuery?
(7 answers)
Closed 8 years ago.
I would like to understand if JavaScript really support Polymorphism ? With function arguments function overloading appears ok but function overriding in classical OO using inheritance ? Is it also supported by JavaScript
Any input pointers would be helpful.
JavaScript is an object oriented language, but not through classical OO. It supports it through prototyping. I would do some research of Java Script and prototyping - Start there

I found it very hard to program a calculator that is similar to a phone calculator.
Yes. using eval() and Function () constructor is easy..
But I think it's not a good practice.
Is there any other way? Maybe in functional approach of programming.
I'm searching for answers,maybe methods on how to really program a calculator in JavaScript.

I was making research about frameworks as a beginner JavaScript learner and I saw people also use libraries so I didn't understand what is the difference between them and why people use these libraries and frameworks ?
Framework means It is use with main programming languages to short the code
Example :- if we built API with only node js then it will take to effort and if we use Express then it will easy to make an API
Library means it will use of a particular area means if we want to generate token then we use only one library if we want to make another like to generate unique id so we want to use another library
Framework is use with whole language but library use for particular area.

What's the difference between object based and object oriented programming language?
Object oriented programming languages follow all concepts belonging to OOP. Object-based language doesn't support all the features of OOPs like Polymorphism and Inheritance Object-based language has in-built object like JavaScript has window object. Object-based languages are JavaScript.

Why is javascript the only client side scripting language implemented in browsers? [closed]

Closed 7 years ago.
Every programming language has many alternatives, however, I could not find any alternative to javascript for accessing the DOM API? Why is this the case?
Thanks.
You have alternatives like Dart, LiveScript, Typescript, Babel and Coffeescript, yet these will be compiled/translated to native Javascript. The reason there is no real alternative is the fact that it is the only standard that is being implemented by all major browser "companies".

Javascript parser generator [closed]

Closed 9 years ago.
I am interested in writing a program using Javascript. This program will parse a custom scripting language. I'm looking for a list of parser generators to evaluate that target Javascript.
These answers were stolen from Javascript parser generator. It would also be nice to have a list of the main features of each, or at least what type of grammar they take.
