You can create a function in JavaScript and add arguments to it. An argument is one or more variables that are declared within the parenthesis of a function definition. The syntax is<\/p>\n

function \u00a0MyFunction(x,y,z)<\/p>\n

{ \u00a0statements;}<\/p>\n

You can also use the return keyword to return a value to the statement.<\/p>\n

function \u00a0MyFunction(x,y,z)<\/p>\n

{ \u00a0return value;\u00a0}<\/p>\n

Example:<\/p>\n

function Area_Rect(width,length)<\/p>\n

{ area=width*length;<\/p>\n

return area;}<\/p>\n

You can call the function by assigning values to the arguments, such as<\/p>\n

document.write(Area_Rect(4,6));<\/p>\n

0r alert (“The area of a rectangle is”+Area_Rect(4,6)<\/p>\n

The area of the rectangle if width=4 and length=6 is:
