Ecmascript arguments object

Note:And othersProgramDifferent design languages, ecmascript does not verify whether the number of parameters passed to the function is equal to the number of parameters defined by the function. All functions defined by the developer can accept any number of parameters (a maximum of 25 parameters can be accepted according to Netscape documentation) without causing any errors. Any missing parameters will be passed to the function as undefined, and additional functions will be ignored.
