海外TECH	DEV Community	How to use built-in array methods in JavaScript	https://dev.to/marina294/how-to-use-built-in-array-methods-in-javascript-10ci	How to use built in array methods in JavaScriptWhen using an array you will find that you have to do long iterations in many situations Do you want to make your code readable and simple Can be done by using built in objects There are various built in objects in JavaScript In this article I will explain how to use the built in array methods What are built in objectsAt first what are built in objects Built in objects provided from the beginning in JavaScript There are four built in objects Array Date Math and String for efficient handling of these objects Each object has special purpose properties and methods associated with it Array methodsThere are many array methods on the list let s see the top of useful methods ADD amp DELETE push add a new element to the end of the array It returns the new length of the array The original array will be modified what is the good thing when you use push method Let s see the example The example above shows two ways to add an element the first method is to specify the element number which is the number added by one from the current last element number of the array you want to add and assign squirrel to it The elements of an array do not have to be contiguous Therefore the index of the element to be added does not have to be the current last index plus one If the number is not the current last index it will be null between the new element The second is push method When you use push method you don t need to count the current last element number of the array But push returns the new length of the array when you print the push you can see the length So when you would like to print the new array you have to write pets unshift Add a new element or multiple elements to the top of an array and returns the number of elements after the addition The original array will be modified It is used in the same way as push method but if you are adding multiple elements at the same time be careful about the order in which they are added Alphabet Result is adding multiple elements at the same time The alphabet starts A Alphabet result starts C Because alphabet is adding elements in each method pop Removes the last element of an array It returns the element and changes the length of the array If the array is empty it returns undefined The original array will be modified shift Removes the top element of an array It returns the element and changes the length of the array If the array is empty it returns undefined The original array will be modified First In First Out FIFO can be created by joining with push method as described above slice start end It retrieves the array elements from the array at the position specified in the start argument to the one before the array element at the position specified in the end argument and returns them as a new array The original array will not be modified The original array will be modified If it only start argument it retrieves the array elements from the array at the position specified in the start argument to the last array element and returns them as a new array The difference between this method and the previous methods is that it does not modify the original array So the Before array and After array are the same length splice index deleteCount element … elementN Removes an element from an array or adds an element to an array and returns the removed element It can also replace a specified range of elements in an array with other elements RemoveIf you do not specify any elements to be added the elements in the specified range will simply be removed AddIf the deleteCount is specified as the element to be removed will be and the element specified in the argument will be added before the element specified in the start index ReplaceIf you specify elements to be added the elements in the specified range will be replaced ORDER sort Sort array elements by string order or by specified order and return the array after sorting The original array will be modified If the element is a string it s very simple But if the element contains a number be careful Whooops It didn t sort Even if the value stored in an element is a number it is not sorted by the size of the number but as a string after the number has been converted to a string Therefore the first character is sorted first resulting in the result as shown above In this case compareFunction is useful CompareFunction is a method of comparing two values and switching their order one by one function compareFunc a b return a lt b Enter fullscreen mode Exit fullscreen mode In this example it takes two arguments a and b and returns the result of comparing a lt b in return By checking whether a is smaller than b the order is switched lt gt and can be used as comparison conditions to change the ascending or descending order Let s see the number example again Ta dah The numbers are now sorted To sort in descending order use the following reverce Sorts of array elements in reverse order The original array will be modified REPEAT forEach It executes a provided callback function once for each array element What is callback function Callback function is Functions passed as arguments and after the function A is executed the function B specified in the argument can be executed if you want iterative processing you can use for loop forEach does not require such initialization and can be written very efficiently The forEach method extracts the elements in the array in order from the top and calls the callback function The callback function is called with the value of the currently fetched element the index of the element and the array itself as arguments It is also possible to retrieve the contents of an object CONVERT map It executes a callback function for each element and returns the result as a new array In the callback function written as an argument the value of the element received as an argument is converted to uppercase using the toUpperCase method and the value is returned as the return value After the same processing is done for all the elements in turn a new array with the returned values as elements is created and returned as the return value of the map method The values of the elements in the new array are all uppercase versions of the values of the elements in the original array but the original array is unmodified because the map method does nothing to the original array It s called undestructive method for example sort splice push shift unshift reverse will be modified of the original array It s called destructive method When you want to back to the original array if you already made destructive method you can t back to the original array Sometimes it make many bugs so please be careful to use destructive method in the code That s all I introduced useful array methods in built in objects Enjoy coding	2021-01-18 16:29:51
