#javascript learning path

As you know, JavaScript is a programming language commonly used in web development. It was originally developed by Netscape as a means to add dynamic and interactive elements to websites. Like server-side scripting languages, such as PHP and ASP, JavaScript code can be inserted anywhere within the HTML of a webpage.

ReactJS basically is an open-source JavaScript library which is used for building user interfaces specifically for single-page applications. It’s used for handling view layer for web and mobile apps. React also allows us to create reusable UI components. React was first created by Jordan Walke, a software engineer working for Facebook.

React allows developers to create large web applications which can change data, without reloading the page. The main purpose of React is to be fast, scalable, and simple. It works only on user interfaces in the application. This corresponds to the view in the MVC template. It can be used with a combination of other JavaScript libraries or frameworks, such as Angular JS in MVC.

Moreover, react is much faster as compared to the JavaScript frameworks. It makes use of the virtual DOM which minimizes the memory consumption and the DOM manipulation expenses.

Advantages of ReactJS

1. Simplicity: ReactJS is just simpler to grasp right away. The component-based approach, well-defined lifecycle, and use of just plain JavaScript make React very simple to learn, build a professional web (and mobile applications), and support it. React uses a special syntax called JSX which allows you to mix HTML with JavaScript. This is not a requirement; Developer can still write in plain JavaScript but JSX is much easier to use.

2. Easy to learn: Anyone with basic previous knowledge in programming can easily understand React while Angular and Ember are referred to as ‘Domain-specific Language’, implying that it is difficult to learn them. For React, you just need basic knowledge of CSS and HTML.

3. Naive Approach: React can be used to create mobile applications (React Native). And React is a diehard fan of reusability, meaning extensive code reusability is supported. So at the same time, we can make IOS, Android and Web application.

4. Data Binding: React uses one-way data binding and an application architecture called Flux controls the flow of data to components through one control point – the dispatcher. It's easier to debug self-contained components of large ReactJS apps.

5. Performance: React does not offer any concept of a built-in container for dependency. You can use Browserify, Require JS, ECMAScript 6 modules which we can use via Babel, ReactJS-di to inject dependencies automatically.

6. Testability: ReactJS applications are super easy to test. React views can be treated as functions of the state, so we can manipulate with the state we pass to the ReactJS view and take a look at the output and triggered actions, events, functions, etc.

Features of ReactJS

1. JSX: In React, instead of using regular JavaScript for templating, it uses JSX. JSX is simple JavaScript which allows HTML quoting and uses these HTML tag syntaxes to render subcomponents. HTML syntax is processed into JavaScript calls of React Framework. We can also write in pure old JavaScript.

2. React Native: React has native libraries which were announced by Facebook in 2015, which provides the react architecture to native applications like IOS, Android and UPD.

3. Single-Way data flow: In React, a set of immutable values are passed to the components renderer as properties in its HTML tags. Component cannot directly modify any properties but can pass a call back function with the help of which we can do modifications. This complete process is known as “properties flow down; actions flow up”.

4. Virtual Document Object Model: React creates an in-memory data structure cache which computes the changes made and then updates the browser. This allows a special feature which enables the programmer to code as if the whole page is rendered on each change whereas React library only render components which actually change.

It can be used with a combination of other JavaScript libraries or frameworks, such as Angular JS in MVC.

ReactJS is a component-based library (not a framework!!) which is used to develop interactive UI’s. Currently, it is the most popular front-end JavaScript library. It deals with View in the MVC (Model - View - Controller). So, if you are dealing with the applications where data keeps on changing in real time, you should go for React.

As in React, the application is composed of different components. Each time any data is added, it will automatically update the specific component whose state has actually changed.

These components are independent building blocks which are integrated together to build the entire application. To understand this better, imagine UI as a tree. Here the starting component becomes the root and each of the independent pieces becomes branches, which are further divided into sub-branches. This keeps our UI organized and moreover, it allows the data and state changes to logically flow from the root to branches and then to sub-branches. One component can refer to other components as well.

Moreover, react is much faster as compared to the JavaScript frameworks. It makes use of the virtual DOM which minimizes the memory consumption and the DOM manipulation expenses.

In this project we will focus on EMI calculator using JavaScript and HTML

A loan is a financial agreement between two parties, a lender and a borrower. Under this agreement, the lender gives a specific amount of money to the borrower with the intent that the amount borrowed is paid back with interest as monthly installments over a predetermined period of time by the borrower. Using an EMI calculator is the easiest way to determine your monthly payouts and balance your budget accordingly. Everyone has to borrow a loan at some point in time in their life whether for buying a car or a house, funding their child’s education or consolidating debts, etc. Thus, loans have become an important part of everyone's life in today’s times. Loans can be availed for various purposes, but the key components on loans are always the same, namely - loan amount, loan tenure and interest rates.

EMI is the payment which the borrower makes every month towards loan repayment of the loan. EMI constitutes the principal amount along with the accrued interest. You can use the EMI calculator to calculate your monthly loan EMI payouts. The borrower just needs to enter the variables of the loan such as the principal amount, tenure and interest rate and it instantly fetches a result which is the EMI.

In this project, we will implement a basic EMI calculator which accepts Loan Amount, Interest Rate and Loan Duration as input from the user and displays the Monthly Interest, Monthly Payment, Total Repayment and Total Interest Cost to the user. All of this will be done by creating the required files in Atom Text Editor.

Benefits of EMI Calculator

The main benefit of an EMI calculator for borrowers is that they get to know how much money they will need to pay towards their loan each month so that they do not end up straining themselves financially and end up in financial distress. Loan EMI calculator helps the borrower decide on an EMI amount which can be comfortably repaid over the tenure of the loan. The benefits of this calculator are just not restricted to the above-mentioned point. There are additional benefits to it, these are:

1. Anytime Access

The calculator can be accessed anytime and anywhere. You can use the calculator any number of times as per your convenience. You need not visit the bank branch or get involved with figuring out complex mathematical calculations; instead, use the EMI calculator.

2. Accurate Results

Doing calculations by hand comes with the risk of making mistakes. Further, doing the same calculations, again and again, can lead to more mistakes and further erroneous results. When you individually calculate EMIs on loans offered by different banks the chance of errors increases further. The EMI calculator helps you in making error-free calculations at the click of a button.

3. Saves you from time-consuming and complex calculations

Comparing the loans offered by different banks can become very boring and time-consuming as you are using the same formula again and again. With pen and paper, you will need to spend long hours to calculate EMIs for a loan. However, with the EMI Calculator, you have the benefit to save your precious time and complete all the lengthy and boring calculations in seconds. So, you can try out as many combinations for amount, tenure and interest rates which you want to from the convenience of your home.

4. Aids the Financial Planning Process

When you calculate EMI for a loan, you know the amount which you will have to pay when you borrow a loan of the specific amount, tenure and interest rate. This helps you plan your finances prior to taking the loan so that your monthly budget does not take a hit. You can also vary the loan parameters to reach the most suitable EMI as per your requirements.
