Scripting Language
JavaScript is a lightweight scripting language made for client-side execution on the browser. Since it is not designed as a general-purpose language and is specially engineered for web applications, the set of libraries is also geared primarily towards web applications.
Interpreter Based
JavaScript is an interpreted rather than compiled language. In that regard, it is similar to languages such as Ruby and Python. The browser runs JavaScript by interpreting its source code line by line. A compiled language, on the other hand, must be compiled into a byte-code code executable. Compilable languages include Java and C++.
Event Handling
An event is a system action or occurrences that communicates about itself so that you can respond to it in some way. For example, if a user clicks a button, the system instructs you to respond to the button click event with an action, such as displaying an information box.
JavaScript allows you to handle events and even create your own.
light weight
Because JavaScript is not a compiled language, it is not converted to byte-code beforehand. It does, however, adhere to the Just-In-Time (JIT) Compilation paradigm. That is, it is converted to bytecode just before running. As a result, JS can be lightweight. JavaScript can be run on even the most basic of devices.
