海外TECH	DEV Community	Introduction to Data Structures and Algorithms with JavaScript.	https://dev.to/muriithigakuru/introduction-to-data-structures-and-algorithms-with-javascript-oab	Introduction to Data Structures and Algorithms with JavaScript In this post we re going to be looking into data structures and algorithms Hopefully this will help to improve your skills and understanding Let s start with a good old fashioned definitionData Structures this is an organization of data so that it can be used efficiently It provides a way so that data can be stored organized retrieved and used efficiently This is an introduction to Data Structures DS so we ll get straight into it ArraysSimilar to other programming languages array objects in JavaScript enable storing a collection of multiple items under a single variable name One important factor about arrays in js are not primitives meaning that the data are not objects and have no underlying methods Examples of primitive types in js are string number bigint boolean undefined symbol and null Let s give some characteristics of arrays JavaScript arrays are resizable and can contain a mix of different data types Arrays must be accessed using integer indices Elements cannot be accessed using strings because they are not associative The first element of the array is always One might think that this is common knowledge but in some languages the first element is FORTRAN COBOLConstructorArray This creates a new Array object Initializing while declaring Creates an array having elements var house new Array Creates an array of undefined elementsvar house new Array Creates an array with element BHKvar home new Array BHK How to create and array fruits array created using array literal notation const fruits Apple Banana console log fruits Apple Banana console log fruits length fruits array created using the Array constructor const fruits new Array Apple Banana console log fruits Apple Banana console log fruits length fruits array created using String prototype split const fruits Apple Banana split console log fruits Apple Banana console log fruits length The above example shows how to create an array from a string separated using a comma We can also create a string from an array using the join method and add a comma separator const fruits Apple Banana const fruitsString fruits join console log fruitsString Apple Banana Functions to use with ArrayArray isArray Returns true if the argument is an array or false otherwise Array prototype reverse Reverses the order of the elements of an array in place First becomes the last last becomes first Array prototype unshift Adds one or more elements to the front of an array and returns the new length of the array Array prototype splice Adds and or removes elements from an array This is just the tip of the iceberg There is more to arrays and to their uses here QueueThink of a queue in a bank It s probably a th century example but applicable The first person to join the queue gets served first and leaves Only then do people who joined after are served first one in first one out This data structure uses the First In First Out FIFO principle Where the dequeue is the removal of the first element and the enqueue is the addition of an element onto the queue as shown below Queue has the following methods enqueue adds an element at the end enqueue functionenqueue element adding element to the queue this items push element This function adds an element at the back of a queue We have used push method of array to add an element at the end of the queue dequeue removes an element at the front of the queue dequeue functiondequeue removing element from the queue returns underflow when called on empty queue if this isEmpty return Underflow return this items shift This function removes an element from the front of a queue We have used shift method of an array to remove an element from the queue front this gets the first element front functionfront returns the Front element of the queue without removing it if this isEmpty return No elements in Queue return this items This function returns the front element of the queue We simply return the th element of an array to get the front of a queue size gets the number of elements in the queueisEmpty shows whether the queue is empty isEmpty functionisEmpty return true if the queue is empty return this items length In this function we have used the length property and if the array length is then the queue is empty StackThe name stack comes from the analogy to a set of physical items Let s use books for instance I ll drop an image just for context We start by placing one book and then each consequent book is placed on top of the other When we need to access the first book placed we ll have to take each book out starting with the one that was placed last Some pancakes would suffice too Let s stack them up This is the Last In First Out LIFO principle JavaScript Array type provides the push and pop methods that allow you to use an array as a stack push The push method allows you to add one or more elements to the end of the array The push method returns the value of the length property that specifies the number of elements in the array If you consider an array as a stack the push method adds one or more element at the top of the stack The following example creates an empty array named stack and adds five numbers one by one at the end of the stack array It is like to push each number into the top of the stack let stack stack push console log stack stack push console log stack stack push console log stack stack push console log stack stack push console log stack Try it out pop The pop method removes the element at the end of the array and returns the element to the caller If the array is empty the pop method returns undefined The following example shows how to pop elements from the top of the stack using the pop method console log stack pop console log stack console log stack pop console log stack console log stack pop console log stack console log stack pop console log stack console log stack pop console log stack gt emptyconsole log stack pop undefined Linked ListA linked list or a singly linked list is a representation of a list of values like an array but each item in the list consists of a single object that has two properties The value property stored inside the objectThe next property node that points to the next objectIt is a collection of nodes in which each node is pointing to next node and last node points to null The linked list data structure value can be of any valid JavaScript data types string number boolean object etc Declaration of type node for Linked ListWe have to create a data structure or Node which contains two parts i e first part will contain the data to be stored and second will store address of next such node We can create this by using user defined data type class Node constructor data this data data this next null Linked lists is a more superior data structure I ll update this post once my understanding is good enough to give conclusive information Conclusion Data structures is fun may be a statement you may not want to hear but they are very interesting The have grown on me to be honest If you re one for solving puzzles I may or may not have a challenge for you Let me not go there though Please don t google the Tower of Hanoi challenge It s too easy for your level Coffee break Cheers	2022-02-21 21:00:37
