It lets you create components, which are reusable, isolated pieces of code that define a part of your user interface. Key Terms Component : Think of components as building blocks for your app. Each part of your app’s UI can be a component, like a button, form, or navigation bar.

JavaScript is the world's most popular programming language. JavaScript is the programming language of the Web. JavaScript is easy to learn. Alongside HTML and CSS, JavaScript is one of the core technologies of the World Wide Web. Over 97% of websites use it client-side for web page behavior. Most web browsers have a dedicated JavaScript engine or JavaScript virtual machine to execute the code. Different engines have different names For example: V8 – in Chrome and Opera. SpiderMonkey – in Firefox. How it Works? The engine (embedded if it’s a browser) reads (“parses”) the script. Then it converts (“compiles”) the script to the machine language. And then the machine code runs, pretty fast.

  Microsoft SQL Server: Microsoft SQL Server is a relational database management system (RDBMS). Applications and tools connect to a SQL Server instance or database, and communicate using Transact-SQL (T-SQL). You can install SQL Server on Windows or Linux, deploy it in a Linux container, or deploy it on an Azure Virtual Machine. SQL Server components and technologies: Database Engine The Database Engine is the core service for storing, processing, and securing data. The Database Engine provides controlled access and transaction processing to meet the requirements of the most demanding data consuming applications within your enterprise.  Integration Services SQL Server Integration Services (SSIS) is a platform for building high performance data integration solutions, including packages that provide extract, transform, and load (ETL) processing for data warehousing.
