海外TECH	DEV Community	Implement JavaScript Array Methods From Scratch	https://dev.to/zagaris/implement-javascript-array-methods-from-scratch-2pl1	Implement JavaScript Array Methods From ScratchThe JavaScript Array class is a global object that is used in the construction of arrays Array is a special type of object that is mutable and it is used to store multiple values In this article we will implement our own array methods from scratch These implementations don t intend to replace the existing methods but to provide a better understanding of how these methods work and their uses MethodsDescriptionindexOf Returns the first index at which a given element can be found in the array otherwise returns lastIndexOf Returns the last index at which a given element can be found in the array otherwise returns reverse Returns the reversed array forEach Executes a provided function once for each array element map Creates a new array with the results of calling a provided function on every element in the calling array filter Creates a new array with all elements that pass the test implemented by the provided function reduce Applies a function against an accumulator and each element in the array to reduce it to a single value For a better understanding of Higher Orders Functions and specifically map filter and reduce methods you can check this article Before we start to implement these methods we will take a quick look on how prototype and this work What is prototype In JavaScript every function and object has a property named prototype by default Prototypes are the mechanism by which JavaScript objects inherit methods and properties with each other Prototypes are very useful when we want to add new properties to an object which will be shared across all the instances function User this name George this age User prototype email george email com User prototype userInfo function console log User name this name User age this age const user new User console log user email george email comuser userInfo User name George User age In the example above we create the function object User that has the properties name and age Then we access the User function object with prototype property and we add the property email and the function userInfo to it What is this The value of this is determined by the object that currently owns the space that this keyword is in runtime binding function User this name George this age this printInfo function console log this this orders orderId printOrderId function console log this const user new User user printInfo User name George age printInfo Function orders orderId printOrderId Function printOrderId user orders printOrderId orderId printOrderId Function printOrderId In the example above we use again the function object User and add the object orders to it The user printInfo prints the this value and in this case it contains all the properties of the User function object The user orders printOrderId prints only the properties of the orders object and that happens because the method printOrderId is called through the orders object Now let s implement the Array MethodsIn order to implement the methods we will access the Array object via prototype property and then we will add our new methods The this keyword inside the methods has the value of the array that is calling the corresponding array method Custom indexOfArray prototype customIndexOf function value for let i i lt this length i if this i value return i return const output console log output customIndexOf In the example above the customIndexOf method takes as a parameter a value and then we iterate the array until we find the corresponding value and return its index Custom lastIndexOfArray prototype customLastIndexOf function value for let i this length i gt i if this i value return i return const output console log output customLastIndexOf In the example above the customLastIndexOf method takes as a parameter a value and then we iterate the array until we find the last corresponding value and return its index Custom reverseArray prototype customReverse function let left let right this length while left lt right let temp this left this left this right this right temp left right return this const output b abc name Jonh console log output customReverse name Jonh abc b In the example above the customReverse method reverses in place the array and returns it Custom forEachArray prototype customForEach function callback for let i i lt this length i callback this i i this const output output customForEach elem gt console log elem In the example above the customForEach method takes as a parameter a callback function and it is applied on every element in the array Also the callback function receives additional the index and the array itself in case that will be used Custom mapArray prototype customMap function map callback const results for let i i lt this length i results push callback this i i this return results let output output output customMap elem gt return elem console log output In the example above the customMap method takes as a parameter a callback function and for each element in the array we apply the callback function and we return the result in a new array Again the callback function receives additional the index and the array itself in case that will be used Custom filterArray prototype customFilter function callback const results for let i i lt this length i if callback this i i this results push this i return results let output output output customFilter elem gt return elem console log output In the example above the customFilter method takes as a parameter a callback function and for each element in the array we apply the callback function and for the values that pass the callback function we return the result in a new array Custom reduceArray prototype customReduce function callback initialValue let value initialValue for let i i lt this length i value callback value this i return value const output const sum output customReduce acc elem gt return acc elem console log sum In the example above the customReduce method takes as parameters a callback function and an accumulator variable and we apply the callback function against the accumulator for each element in the array until to reduce it to a single value You can
