Object Creation In this example, an object named “car” has been created with the following properties: We also use console.log() to display this object and all the properties we wrote in the console. The properties of each object can be accessed using dot syntax. Object methods and using “this” Objects in JavaScript can contain not only properties, but also methods. Methods are functions of an object. The keyword “this” is used inside methods to refer to the object on which the method is called. Method abbreviation The new Javascript ES6 now allows you to write methods in a shorter format. Object Arrays These are data structures that contain many objects in an order. Creating and displaying an array of objects Here is an array of cars, which contains 3 car objects, all objects have the same properties. If we want to see the data for a specific car, we can reference the car’s position in the array. And in this object, I can retrieve the elements with the “dot syntax”, as above: forEach Loop To see all the models, we use the forEach loop again: Object Array Methods push(), pop(), shift(), unshift(), splice(), slice(), forEach(), map(), filter(), reduce(), sort(), etc. push() – Adds a new object to the end of the array. unshift() – Adds a new object to the beginning of an array. splice() – Deletes and adds at the same time. Array Searching Note that this only returns one element that is found. This method finds the first match and returns it. Note that this only returns one element that is found. This method finds the first match and returns it. Array Filtering For example, we have numbers and we want to get an even number from them: For cars, we can, for example, go to car.year and filter for those newer than 2018. Array Sorting The difference with filtering is that it does not find a new array, it only changes the array that is given. Simply sorting an array of objects does not work correctly. Therefore, we need to use a comparison function.
