As a powerful tool for text substitution, search and extraction in pattern matching, the application of regular expression (Regular Expression) has been gradually infiltrated into network development from the UNIX platform, as the server-side/client Script development language JScript, More and more regular expression applications are being incorporated into them to make up for the inadequacy of their ability to deal with the text. Here, we use the JS

In JScript, the undefined identifier is used to indicate what is undefined? What is the difference and connection between it and "undefined" (including?

The scope of variables defined by var in JScript does not remember when the JScript syntax tutorial was read. it is completely legal to ignore the var keyword when declaring a variable. At that time, because JavaScript was thought to be the loosely-typed language, var may be a decoration. However, facts often prove that the result is unreliable.

organization methods to make JS conform to basic object-oriented features, it paves the way for further application of some design patterns of software engineering. JScript has built-in classes, such as string, array, and math. You can create objects from these class instances and use the attributes and methods. With this alone, JavaScript cannot be said to conform to the characteristics of object-oriented languages. An object-oriented language sho
