What is scope of variables and types of scope variable?, • The scope of a variable is the life time of a variable of source code in which it is defined., • A global variable has global scope; it can be defined everywhere in the JavaScript code., • Variables declared within a function are defined only within the body of the function are called Local, Variables and have local scope., 3. Write a notes to type casting in JavaScript, • Type conversion is the act of converting one data type into a different data type which is also called as, casting., Type of casting:, 1. Implicit casting, 2. Explicit casting, 4. How many Literals in JavaScript and mention its types., • A literal is a fixed value given to a variable in source code., • Literals are often used to initialize variables., • Values may be Integer, Floating point, Character, String and Boolean., 5. What is conditional operator give suitable example., The ?: is the conditional operator in JavaScript, which requires three operands, hence it is called the, ternary operator., SYNTAX:, , var variablename = (condition) ? value1 : value2;, , EXAMPLE:, , var result = (10>15) ?100 :150;, , 6. What are the comments in Java Script?, • Single-line comments begin with a double slash (//), causing the interpreter to ignore everything from, that point to the end of the line., • Multiple line comments begins with /* and ends with */., 7.

Brief the basic data types in Java Scripts., The three basic data types in Java Scripts are,, 1. 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)., 2. Numbers can be integer or floating-point numerical value and numeric literals are specified in the, natural way., 3. Boolean literals are indicated by using true or false directly in the source code., 3. Write note on string Operator., • The + operator is also called as the string concatenation operator., • Because string concatenation has precedence over numeric addition,, concatenation if any of the operands are strings., Example:, , + will be interpreted as string, , 4. Write about <script> tag, • The <script>... </script> tag containing JavaScript can be placed anywhere within in the web page,, but it is normally recommended that should be kept it within the <head> tags., • The <script> tag alerts the browser program to start interpreting all the text between these tags as a, script commands., SYNTAX:, <script language="javascript" type="text/javascript">, JavaScript code, </script>, ATTRIBUTES:, Language − This attribute specifies that the scripting language., Type − This attribute is used to indicate the scripting language and its value should be set to, text/javascript"., 5.
