Logical operators perform logical (boolean) operations. Logical operators combine or invert boolean values. Once comparisons are made, the logical operators && (AND), || (OR) and ! (NOT) can be used to create more complex conditions.
Best practice is to use logical operators on boolean operands., However, operands of any type can be combined. The strict rules are as follows:
(i) For & & (AND) the result is false if the first operand is false; otherwise, the result is the Boolean value of the second operand.
(ii) For || (OR) the result is true if the first operand is true; otherwise, the result is the Boolean value of the second operand.
(iii) For | (Not)the result is true if the operand is false; otherwise, the result is true.

JavaScript can be implemented using .... tags. The tag containing JavaScript can be placed anywhere within in the web page, but it is normally recommended to be kept within the \(<head>\) tags. The tag alerts the browser program to start interpreting all the text between these tags as a script command.

One of the built-in features of JavaScript is the ability to concatenate strings. The + operator performs addition on numbers but also serves as the concatenation operator for strings. Because string concatenation has precedence over numeric addition, + will be interpreted as string concatenation if any of the operands are strings. + operator which is also called as the string concatenation operator.

The basic data types in JavaScript are Strings, Numbers, and Booleans.
(i) A string is a list of characters, and a string literal is indicated by enclosing the characters in single or double quotes. Strings may contain a single character or multiple characters, including whitespace and special characters such as \n (the newline).
(ii) Numbers can be integer or floating-point numerical value and numeric literals are specified in the natural way.
(iii) Boolean can be any one of two values: true or false. Boolean literals are indicated by using true or false directly in the source code.

(i) JavaScript programming language is used to develop interactive web pages called Dynamic Web pages.
(ii) User entered data in the Dynamic Web page can be validated before sending it to the server. This saves server traffic, which means less load on your server
(iii) JavaScript includes items such as Texboxes, Buttons, drag-and-drop components and sliders to give a Rich Interface to site visitors.
