Javascript Object #3 |
https://dev.to/samr/javascript-object-3-ep7

Javascript Object From the last Post We have seen what is Object and How to access the properties inside of them while we went through the chapter two about Object we have discussed about two methods of accessing the Object Properties and we also concluded with what is best on my opinion Well most of you may like easy and non tricky method Dot Notation but we have a drawback with that method we can t completely nullify the issue but we can do something to Prevent the error occuring while accessing them In the Post we are going to see how to check wheater the Property is present in the Object or not JavaScript provides you with three common ways to check if a property exists in an object Use the hasOwnProperty method Use the in operator Compare property with undefined hasOwnProperty The Javascript Object Prototype has a method called hasOwnProperty that returns true if the Property we are looking for exist otherwise it will return False The Basic Syntax is let result targetObject hasOwnProperty propertyName here targetObject is our Object and PropertyName is the specific Property name we are searching for let s see this with an example let person firstName Sam lastName r we can check it by let result person hasOwnProperty firstName console log result true let result person hasOwnProperty age console log result false Note that the hasOwnProperty looks for the property in the own properties of the object All Object Inherit a Property called toString of the Object the hasOwnProperty will not detact it as a property let result person hasOwnProperty toString console log result false the in operatorThe in operator returns true if a property exists in an object If a property does not exist in the object it returns false The Syntax is propertyName in targetObjectlet s have an example using the in operator let person firstName Sam lastName r let result firstName in person console log result trueresult age in person console log result false Both in operator and the hasOwnProperty looks similar but there is a key difference in it that was while checking for Object inherited method toString in Object hasOwnProperty will not detect that but in operator will detatct that let person firstName Sam lastName Rachael let result toString in person console log result true Comparing the property with undefinedWhen you access a non existing property of an object you will get undefined Therefore you can compare the property with the undefined to check if a property exists in an object let person firstName Sam lastName Rachael let result person firstName undefined console log result true uphere we have checked for the not equal to undefined And in our Case yes firstName Property do exist and it s not equal to Undefined and retured True But there s an another problem in these method If an object has a property whose value is undefined then comparing the property with undefined will return an incorrect result For example let person firstName Sam lastName Rachael age undefined let result person age undefined console log result false In this example the age property does exist in the person object However its initial value is undefined Therefore comparing the person age with undefined returns false which is not expected Yes That s for now In the meantime thanks for your time Sam |
