Here’s a roadmap for learning the JavaScript language. There are many features in the language, but luckily you don’t have to learn all of them – you can focus on important parts. And that is the JavaScript language itself. You’re wondering how are you going to tackle all of these technologies – even counting the number of different frameworks out there seems overwhelming.īut, before you dive deeper into any framework, there is one building block that you should have under your belt. If you’re new to JavaScript programming, all the buzzwords in the scene can make your head spin: ES6, Node.js, TypeScript, Angular, React, Aurelia. Roadmap for learning the JavaScript language: In fact, Angular is the second most popular framework which is used among developers. Some of the top companies across world such as PayPal, Fitbit, Barnes& Noble, Teradata etc are using Angular. Incase you want to go for full-stack development, I would recommend you to go for MEAN stack. MEAN stands for - Mongo DB, Express.js, Angular, Node.js, while MERN stands for Mongo DB, Express.js, React and Node.js. The two technology stacks differ in front-end frameworks, while back-end frameworks remains the same.Īs a full-stack Javascript developer, you can earn anywhere between 10–12 LPA. This of course depends on the proficiency in technologies. Currently, MEAN and MERN are two popular Javascript-based technology stacks that you can go for. Full-Stack Javascript developer- This where you need to know technologies for both front-end and back-end development.

Broadly, this is termed as hosting.Īs a back-end developer, you can earn anywhere between 6–10 LPA.ģ.

Plus, you would need to learn how to set-up cloud servers like AWS, Google cloud etc. Back-end developer- In addition to Javascript, here you would need to know Javascript-based back-end frameworks and technologies including Node.js, Express.js, Meteor.js and databases such as MySQL, MongoDB,etc.

It should’ve really been called something like, "prototypeToInstall", since that’s what it is.Īnd _proto_ is that “installed prototype” on an object (that was created/installed upon the object from said constructor() function) Prototype is used by constructor() functions. Current standards provide an equivalent Object.getPrototypeOf(O) method, though de facto standard _proto_ is quicker. _proto_ is internal property of an object, pointing to its prototype. It is the prototype of objects constructed by that function. Prototype is a property of a Function object. prototypeis the object that is used to build _proto_ when you create an object with new _proto_ is the actual object that is used in the lookup chain to resolve methods, etc.
