how to pass object as parameter in javascript code example

Example 1: parameters types in javascript

/**
 * My function description
 * @param {String} a
 * @param {String} b
 * @param {Number} amount
 * @example
 * // returns "fooBar fooBar"
 * myFunction('foo', 'Bar', 2)
 * @returns {String}
 */
function myFunction(a, b, amount){
  //do stuff
}
//Note that javascript is not a statically typed language and therefore you
//will not recieve any syntax errors for passing in the wrong types.
//The above code works in Visual Studio Code and intellisense.

    }
};
console.log(fac(3)); // 6
