js parameter argument code example

Example 1: argument vs parameter javascript

var foo = function( a, b, c ) {}; // a, b, and c are the parameters

foo( 1, 2, 3 ); // 1, 2, and 3 are the arguments

Example 2: how to access any argument in javascript

function example() {
	console.log(arguments);
  	console.log(arguments[0]);
} // Console outputs an array of each argument with its value

example('hi', 'hello'); 
// Outputs: 
// ['hi', 'hello']
// 'hi'
