Difference between JavaScript and C++

Key difference: Even though their names suggest that Java and JavaScript must be related somehow, it is just not true. JavaScript is an interpreted computer programming language. The main difference between Java and JavaScript is that while Java is a programming language, JavaScript is scripting language. It is a prototype-based scripting language that is dynamic, weakly typed, and has first-class functions. C++ is a general-purpose programming language. It was developed from the original C programming language. C++ is a statically typed, free-form, multi-paradigm and a compiled programming language.

Even though their names suggest that Java and JavaScript must be related somehow, it is just not true. JavaScript is an interpreted computer programming language. The main difference between Java and JavaScript is that while Java is a programming language, JavaScript is scripting language. It is a prototype-based scripting language that is dynamic, weakly typed, and has first-class functions. However, like Java, JavaScript is heavily influenced by the C programming language. JavaScript also borrows many names and naming conventions from Java, but it does have very different semantics than Java.

JavaScript takes its key design principles from the Self and Scheme programming languages. It is a multi-paradigm language that supports object-oriented, imperative, and functional programming styles.

JavaScript was formalized in the ECMAScript language standard and was originally implemented as part of web browsers. It allowed client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that was displayed. However, JavaScript is also used in applications outside of web pages, such as in PDF documents, site-specific browsers, and desktop widgets. Furthermore, newer and faster JavaScript VMs and frameworks have also increased the popularity of JavaScript for server-side web applications.

There are various similarities between Java and JavaScript, such as both have a C-like syntax. They are both object-oriented and typically sandboxed, especially when used inside a browser. Also, JavaScript was designed with Java's syntax and standard library in mind. All Java keywords were reserved in original JavaScript. JavaScript's standard library follows Java's naming conventions, and JavaScript's Math and Date objects are based on classes from Java 1.0. However, they are much more different than they are similar.

C++ is a general-purpose programming language. It was also developed from the original C programming language. It was developed by Bjarne Stroustrup at Bell Labs starting in 1979. C++ was originally named C with Classes. It was renamed C++ in 1983.

C++ is a statically typed, free-form, multi-paradigm and a compiled programming language. The C++ programming language is widely considered to be an intermediate-level language, as it made up of both high-level and low-level language features. As compared to C, C++ incorporates object oriented features, such as classes, and other enhancements.

C++ has taken over some of the popularity of the C language. C++ is now currently implemented on a wide variety of hardware and operating system platforms. It is considered to be an efficient compiler to native code. It also incorporates systems software, application software, device drivers, embedded software, high-performance server and client applications as part of its application domains, as well as entertainment software such as video games.

C++ originally started out as an enhancement to C. It was designed to be source-and-link compatible with C. It added classes, virtual functions, operator overloading, multiple inheritance, templates, exception handling, etc. However, it eventually developed enough to be considered a programming language in its own right. It was originally ratified in 1998 as ISO/IEC 14882:1998.

C++ is now commonly used for hardware design. The design is first described in C++. It is then analyzed, architecturally constrained, and scheduled to create a register-transfer level hardware description language. It would do this through high-level synthesis.

Both free and proprietary C++ compiler software is available in the market. Some examples of these software include the GNU Project, Microsoft, Intel and Embarcadero Technologies. C++ has also had a major influence on other programming languages such as C# (C Sharp) and Java.

JavaScript and C++ are similar in the regard that they are both based on the C programming language. Furthermore, they are also both based on OOP (Object-oriented programming). However, the main difference between the two is that while C++ is a programming language, JavaScript is a scripting language.
