Why JavaScript?

The difference between JavaScript and Java

Java and JavaScript are oftentimes confused. However, these two languages could not be more different.

Typed language

Java is a strongly-typed language, which means that it forces developers to define code variables with data type restrictions (i.e., string data can’t be stored in an integer variable). JavaScript is a weakly-typed language and is more flexible in these terms.

Applications

Java is used extensively in enterprise application development, while JavaScript is widely utilized in web development.

Debugging

Java rapidly shows any structural issue with the code and can resolve errors in real-time as it’s being compiled. Being all-text, JavaScript doesn’t detect any faults during the compilation process since it does not debug code while compiling.

JavaScript. Popular through the years.

The reasons for JavaScript popularity are its versatility and the array of use cases. It can be employed to create a small plug-in, a standalone application, or a complex platform with a robust set of features. Powered by constant updates and support of the language, a wide range of libraries and APIs, it remains one of the most popular programming languages. In the end, we get a smoothly working lightweight application with an astonishing design taking almost no time to develop.
