What is JavaScript?
JavaScript ES6 (also known as ECMAScript 6) is a client-side, cross-platform, prototype-based scripting language developed by Brendan Eich. JavaScript is commonly used in front-end web development to create dynamic and interactive web applications. JavaScript is dynamically typed. This means that all type checking is done at compile time. A dynamically typed language prioritizes developer efficiency and allows less code to complete a project. Dynamically typed languages also tend to be more flexible, but they generally provide less optimized code because they need to be run first to see if there are any errors. JavaScript also runs directly in web browsers, so no additional resources are required to run JavaScript code. However, it’s still hard to debug a set of bugs at once instead of fixing them on the fly. Note:
Other examples of dynamically typed languages are Python, PHP, Perl, and Ruby. Since its introduction in 1995, JavaScript has gone through several iterations to improve its capabilities and simplify software development. It can now also be used to create interactive games. Plain JavaScript started as a very simple language designed to be embedded in web pages as short snippets of code. This was because his web browser at the time could only really handle a few dozen lines of code, making it unbearably slow to use. Today’s modern browsers can run JavaScript applications with hundreds of thousands of lines of code. JavaScript also benefits from a large and engaged community, extensive documentation, and many libraries and frameworks. Additionally, JavaScript supports many client-side APIs that can reduce the amount of code that software developers have to write. For these reasons, JavaScript is a popular choice for most development teams. However, JavaScript was not originally intended for use in large-scale projects. Small projects can certainly be debugged, but trying to debug large projects in JavaScript can be a tedious and time-consuming process.
Note:
You may not think JavaScript is an object-oriented programming language, but he actually has strong support for OOP. What is TypeScript? TypeScript is an open source programming language that started in 2010 as an internal Microsoft product. TypeScript was published on GitHub([2]) in late 2012. Since TypeScript is considered a strict superset of ECMAScript 2015, JavaScript programs can also be considered TypeScript programs. Unlike JavaScript, TypeScript is a statically typed programming language. As a static type checker, TypeScript checks the behavior of certain variables before running your program. This is true even if you declare the variable without specifying its type. In such situations, TypeScript can automatically assign types to declared variables. This is called type inference and is a built-in feature of other languages such as Kotlin and Scala. Once a variable’s type is assigned, TypeScript applies it throughout your code. This improves consistency and allows you to debug potential errors before compiling. The trade-off of this additional support is that you lose some of the flexibility that JavaScript developers are accustomed to.
Note:
Statically typed languages include Java, C, and C++. Static typing requires the programmer to specify the data type of each variable that it declares. TypeScript was built around 11 design goals.
Microsoft has identified 11 key goals to drive TypeScript development. Identify potential bugs statically. It provides a way to structure larger bodies of code. Avoid long running programs. Compile to clean, recognizable JavaScript
