Complex Objects Can Contain Most of the JavaScript Values as Properties
A complex object can hold any permitted JavaScript value. Below, I
create an Object() object called
myObject and then add properties
representing the majority of values available in JavaScript.
<!DOCTYPE html><html lang="en"><body><script>
var myObject = {};
/* contain properties inside of myObject representing most of the native
JavaScript values */
myObject.myFunction = function() {};
myObject.myArray = [];
myObject.myString = 'string';
myObject.myNumber = 33;
myObject.myDate = new Date();
myObject.myRegExp = /a/;
myObject.myNull = null;
myObject.myUndefined = undefined;
myObject.myObject = {};
myObject.myMath_PI = Math.PI;
myObject.myError = new Error('Crap!');
console.log(myObject.myFunction,myObject.myArray,myObject.myString,
myObject.myNumber,myObject.myDate,myObject.myRegExp,myObject.myNull,
myObject.myNull,myObject.myUndefined,myObject.myObject,
myObject.myMath_PI,myObject.myError);
/* works the same with any of the complex objects, for example a function */
var myFunction = function() {};
myFunction.myFunction = function() {};
myFunction.myArray = [];
myFunction.myString = 'string';
myFunction.myNumber = 33;
myFunction.myDate = new Date();
myFunction.myRegExp = /a/;
myFunction.myNull = null;
myFunction.myUndefined = undefined;
myFunction.myObject = {};
myFunction.myMath_PI = Math.PI;
myFunction.myError = new Error('Crap!');
console.log(myFunction.myFunction,myFunction.myArray,myFunction.myString,
myFunction.myNumber,myFunction.myDate,myFunction.myRegExp,myFunction.myNull,
myFunction.myNull,myFunction.myUndefined,myFunction.myObject,
myFunction.myMath_PI,myFunction.myError);
</script></body></html>
