II. Answer To The Following Questions

Question 1.
What is a function in JavaScript?
Answer:
A function is a block of JavaScript code that is defined once but may be executed or invoked any number of times. Functions are used to encapsulate code that performs a specific task.

Question 2.
What is the use of function?
Answer:
Sometimes functions are defined for commonly required tasks to avoid the repetition entailed in typing the same statements over and over. More generally, they are used to keep code that performs a particular job in one place in order to enhance re-usability and program clarity.

Question 3.
Write a note on Library functions?
Answer:
Pre-defined functions are already defined in the JavaScript library which are also called Library functions. For example isNaN( ), toUpperCase( ), toLowerCase( ), length( ), alert( ), prompt( ),write( ) etc… are pre-defined functions.

Question 4.
Write a note on user defined functions?
Answer:
User-defined functions allow the programmer to modularize a program. Most computer programs that solve real-world problems are much large, occupy more space in the computer memory and takes more time to execute. Hence such large programs are divided into small programs are called modules.

Question 5.
Write the syntax of functions?
Answer:
The format of a function definition is –
Function function-name(parameters list)
{
Declaration of variable Executable statements;
}
