Description

JavaScript is a lightweight interpreted programming language with rudimentary object-oriented capabilities. Syntactically, the core JavaScript language resembles C, C++ and Java, with programming constructs such as the if statement, the while loop, and the && operator. The similarity ends with this syntactic resemblance, however. JavaScript is an untyped language, which means that variables do not have to have a type specified.

The and tags are used to embed JavaScript code within an HTML file.
