Objects in JavaScript For beginners |
https://dev.to/ericawanja/objects-in-javascript-for-beginners-38l2
|
Objects in JavaScript For beginnersObjects are dictionary like items which are defined as a key value pair It is a reference data type That is object variables are assigned reference pointer that points the location storage in memory Loosely speaking if you modify the assigned variable pointer then the original value in the memory will be modified too Unlike arrays objects are unordered hence you cannot use indexes to access items Don t worry we will discuss later how to access items Example of an object let person firstName John lastName Doe How to create an object in JavaScriptObject literalThis is the easiest way to create objects in JavaScript where you define and initialize the object inside curly brackets with a key value pair The key which is also referred to as a property name must be a string while the value property can be of any data type For instance let person firstName John lastName Doe The variable person has two properties i e firstName and lastNameNew Object keywordWe can use the new Object constructor to initialize an object Notice in this case you will have to add the properties later const person new Object initializing an objectperson firstName John adding property firstName with a value of Johnperson lastName Doe Object constructorObject constructor function acts as a blueprint for creating multiple objects The key values are passed as function parameters function Student first last age eye this firstName first this lastName last this age age this eyeColor eye lets create student and student objectsconst student new Student John Doe blue const student new Student Sally Rally green When should you use objectsObjects are useful in storing with a key value pairUseful in grouping values with similar characteristics together to make your code more readable Drawbacks of JavaScript objectsObject properties are unordered hence does not support accessing items with indexes You must know the property name Does not support operations such as adding or removing an item at a particular position How to access items in an objectObject properties can be accessed using a dot or bracket notation For instance let person firstName John lastName Doe person firstName outputs John person lastName outputs Doe Notice that the property is passed as a string in the bracket notation If you access an unassigned property in an object it outputs undefined and not nullperson age undefinedThe dot operation can only be used if the property is a valid JavaScript identifier A dot operation will throw an error if the property name has a space hyphen or if the property is dynamically determined In such circumstances use the bracket notation let address building no street North st street state CA country USA address building no How to add and change properties in an objectAdding properties in objects is so simple Access the property and assign a value to it Let s add age and building no to our person object Similarly you can change a value property by assigning it to a new value let person firstName John lastName Doe person age person building no change the firstName to Janeperson firstName Jane console log person age console log person building no How to delete properties in an objectThe delete operator is used to delete both the property and its value in objects delete person age delete person building no Before deletion person age person building no after deletion person age undefined person building no undefined How to iterate an objectThe fastest way to transverse an object is using for in loop For instance let person firstName John lastName Doe for let x in person console log x outputs all the properties How to check if a property exists in an objectUse the in operator to check if a certain property exists in the object It returns a boolean age in person true country in person falsesimilarly the hasOwnProperty method can be used to check if the property exist person hasOwnProperty age true in vs hasOwnProperty in returns true if the object exists in the object even if it has been inherited from another object let obj age const obj Object create obj console log age in obj outputs trueHowever hasOwnProperty method returns true only if the property is a direct property of the object let obj age const obj Object create obj obj name John adding the name propertyobj hasOwnProperty age falseobj hasOwnProperty name trueNote obj hasOwnProperty age returns false because age is not a direct property of the obj object methodsAn object method is an object property that is a function let person firstName John lastName Doe fullName function return this firstName this lastName console log person fullName John Doethis keyword is used to refer to the objectNote You can also pass parameters in the method ConclusionObjects are a very important data type in JavaScript since it forms a building block of many other data structures such as linked list and modern JavaScript classes |

Maps in JavaScript |
https://dev.to/ericawanja/maps-in-javascript-3ng2
|
Maps in JavaScriptMap data structure was introduced in ES It has a similar key value pair syntax as the objects How to create a mapYou can create a map by passing an array of the key value pairs into the new Map constructorconst fruits new Map apples bananas oranges console log fruits Map apples gt bananas gt oranges gt Alternatively you can use set method to add elements into the map const fruits new Map fruits set apples fruits set bananas fruits set oranges console log fruits Map apples gt bananas gt oranges gt What are the differences between a map and objectSame as objects maps store key value pair elements However the two are significantly differentFeatureMapObjectsKeys A map key can be any value This includes objects functions or primitivesStrictly objects key must be a string or symbol data typeLengh Map has a size property which returns the length of the map The length of an object can only be determined by iterating and counting all the elements manuallyIterationDirectly iterableYou cannot iterate an object directly However you can do so by implementing other methodsDefault keysMap only contains keys that are explicitly declared Hence does not contain default keysSince objects has a prototype it contains default keys which can collide with other keys Map operationsadd element set method is used to add elements to a map The set method receives the key value pair of the new element as a parameter fruits set apples get elementget method receives the a key parameter of the elementfruits get apples outputs Remove elementdelete method deletes element from the map fruits delete apples Clear Mapclear method removes all the elements from a mapfruits clear Trasverse a mapforEach can be used to access the items in a list sequentiallyconst fruits new Map apples bananas oranges fruits forEach key value gt console log key value output apples bananas oranges keys returns an iterable list of the keys Similarly values returns an iterable list of the valuesconst fruits new Map apples bananas oranges console log fruits keys outputs apples bananas oranges console log fruits values outputs entries transverses the map and returns an array of key value pair key values const fruits new Map apples bananas oranges console log fruits entries apples bananas oranges Find size of a mapsize property returns the length of the mapfruits size outputs SummaryEven though objects and maps look quite similar they are quite different Map have size property and the keys can be anything including functions and objects Objects do not have size property while the keys must be strictly strings |

Apple expected to further diversify MacBook production within ChinaA new report claims that Apple will diversify its MacBook Pro production so that it is made in more sites around China Apple has already been working for some years to spread MacBook Pro production over multiple companies and countries In Apple and many other Big Tech firms were said to be looking to move away from China to avoid then threatened US tariffs Then in Apple specifically asked Foxconn to open a plant in Vietnam for instance Foxconn got approval for that from local Vietnamese authorities in Since then too China has added an impetus to Big Tech firms moving away because of energy and coronavirus issues Read more |
