海外TECH	DEV Community	Compare Anything in JavaScript with Just A Function	https://dev.to/rasaf_ibrahim/compare-anything-in-javascript-with-just-a-function-5g1a	Compare Anything in JavaScript with Just A FunctionIn this article we will create a function that can compare not only strings numbers and booleans but also arrays and objects The arrays and objects that this function will compare can have nested arrays and nested objects Also the objects can not only have enumerable properties but also nonenumerable If you want to see a preview go to the last section Preview Table of ContentsStep Creating the functionStep Checking NullStep Checking String and Number and BooleanImportant InfoStep Checking TypeStep Checking total number of propertiesStep Checking Property NamesStep Checking Property ValuesStep The Last StepFull CodeTesting  Step Creating the function Let s name this function compareAnything and this function will accept two arguments first amp second function compareAnything first second We can pass two values as arguments This function will return a boolean value after comparing those values   Step Checking Null In this step we will check whether any of the arguments is null If any argument is null we have nothing to compare we will simply return false But if none of them are null we will move forward to the next step function compareAnything first second if first null second null return false   Step Checking String and Number and Boolean It s easy to compare strings numbers and booleans We just need to use a strict equality operator function compareAnything first second Using the strict equality operator if first second return true If the arguments are equal we are returning true But if they are not equal then surely they are not strings or numbers or booleans Maybe they are objects or arrays So we will move forward to the next step  ️ Important Info  Why it s a little bit tough to compare two objects Before going to step let s understand why it s tough to compare two objects In JavaScript objects are stored by reference That means one object is strictly equal to another only if they both point to the same object in memory This GIF is collected from panjee com and modified afterward  const obj score const obj obj const obj score obj obj true same referenceobj obj false different reference but same keys and values Arrays are objects Arrays are a special type of object The typeof operator in JavaScript returns object for arrays let a console log typeof a objectSo from now we will only focus on comparing two objects If we can make functionality to compare two objects that functionality will also compare two arrays automatically   Step Checking Type In this step we will make sure that the type of the argument is object If any of the arguments is not an object we will return false function compareAnything first second if typeof first object typeof second object return false Note The typeof operator in JavaScript returns object for arrays too So in this step we are checking for both arrays and objects   Step Checking the total number of properties In the last step we have made sure that both arguments are objects In this step we will check whether both objects have the same number of properties or not If they don t have the same number of properties we will return false function compareAnything first second Using Object getOwnPropertyNames method to return the list of the objects properties let first keys Object getOwnPropertyNames first let second keys Object getOwnPropertyNames second Using array length method to count the number of total property if first keys length second keys length return false Could we use Object keys instead of Object getOwnPropertyNames No Because Object keys can t return Nonenumerable property s name but Object getOwnPropertyNames can   Step Checking Property Names In the last step we made sure that both objects have the same number of properties Now we need to make sure that the properties names of both objects are the same If they are not the same we will return false But if they are the same we will move forward to the next step function compareAnything first second Iterating through all the properties of the first object with for of method for let key of first keys Making sure that every property in the first object also exists in the second object if Object hasOwn second key return false Could we use Object hasOwnProperty instead of Object hasOwn No Because Object hasOwnProperty can t check a Nonenumerable property s name but Object hasOwnProperty can Also Object hasOwn is intended as a replacement for Object hasOwnProperty so we are using Object hasOwn here   Step Checking Property Values In the last step we made sure that the property names of both objects are the same Now we will check whether the property values of both objects are the same or not  This step is a little bit tricky because  The property values can not only be strings numbers or boolean but also nested objects Just checking with strict equality operator would be enough if the values were string or number or boolean but it wouldn t be enough for an object because the nested object will have its own properties Let s suppose that the nested object has another object inside it as a property What will we do Will we check one by one  Solution  In the step we created this compareAnything function and this function not only checks the strict equality operator but also it checks null or not object or not properties of objects are the same or not So actually we need a function like this compareAnything to check any nested object s properties Fortunately we don t need to create any new function because there is a term known as the recursive function A recursive function is a function that calls itself during its execution So we can use this compareAnything function as a recursive function Now let s use this compareAnything function to check whether the property values of both objects are the same or not If they are not the same we will return false function compareAnything first second for let key of first keys Using the compareAnything function recursively and passing the values of each property into it to check if they are equal if compareAnything first key second key false return false NoteAs the compareAnything is inside a loop So it will continue to execute itself till it finishes checking all the nested objects   Step The Last Step If we are in this step that means no other step s condition matched As we have checked almost all possible ways in which the objects are not the same and none of those conditions matched so now we can surely say that the objects are the same So we will simply return true in this step function compareAnything first second for let key of first keys return true   Full Code function compareAnything first second Checking if any arguments are null if first null second null return false Checking if the types and values of the two arguments are the same if first second return true Checking if any argument is none object if typeof first object typeof second object return false Using Object getOwnPropertyNames method to return the list of the objects properties let first keys Object getOwnPropertyNames first let second keys Object getOwnPropertyNames second Checking if the objects length are same if first keys length second keys length return false Iterating through all the properties of the first object with the for of method for let key of first keys Making sure that every property in the first object also exists in second object if Object hasOwn second key return false Using the compareAnything function recursively calling itself and passing the values of each property into it to check if they are equal if compareAnything first key second key false return false if no case matches returning true return true
