If a function is not a method of a JavaScript object, it is a function of the global object (see previous chapter). The example below creates an object with 3 properties, firstName, lastName, fullName. Example constperson = { firstName:"John", ...
Building up objects with methods is pretty much the same. Using the function operator to directly assign the method to the object means not having to go looking for the implementation. If you’re worried about performance, use theobject prototypeto declare the method only once for all the obje...
Theapply()method accepts arguments in an array: Example constperson = { fullName:function(city, country) { returnthis.firstName+" "+this.lastName+","+ city +","+ country; } } constperson1 = { firstName:"John", lastName:"Doe" ...
