These values are inherently simple, and do not represent values that can be made up of other values. a. info | 13 Examine the code below and ask yourself if the string, number, boolean, null, and undefined values could be more complex. Contrast this to what you know of an Object() instance or Array() instance or really any complex object. log(myString, myNumber, myBoolean, myNull, myUndefined); /* Consider that a complex object like array or object can be made up of multiple primitive values, and thus becomes a complex set of multiple values.
In the example above, we copied, or cloned, the myString value to the variable myStringCopy. When we updated the my String value, the myStringCopy value still had a copy of the old myString value. Re‐ member this and contrast the mechanics here with complex objects (discussed below). info Primitive Values Are Equal by Value Primitives can be compared to see if their values are literally the same. , 10 = = = 10). The same, of course, would apply if you compare the primitive string 'foo' to another primitive string with a value of 'foo'.
