One factor attributing to a scripting languages success is the ease of updating. Although scripting languages may have less access and are slower, they can be very powerful tools. Also, compilers read and analyze the code only once, and report the errors collectively that the code might have, but the interpreter will read and analyze the code statements each time it meets them and halts at that very instance if there is some error. Generally, compiled languages run faster than scripting languages because they are first converted native machine code. One common difference between a scripting language and a programming language is that, while a programming language is typically compiled first before being allowed to run, scripting languages are interpreted from source code or bytecode one command at a time.

Javascript will not be able to access your file system. These languages usually have less access to the systems native abilities since they run on a subset of the original programming language. These are designed for integrating and communicating with other programming languages. Scripting languages usually sits behind some programming language. Scripting languages are programming languages mostly (but not necessarily exclusively) used for scripting that don't require an explicit compilation step.
