QUESTION

How to implement deque data structure in javascript?

Asked 2020-Feb-04 at 14:13

I'm Learning data structure with javascript

and my focus now on how to implement deque?

Edite: from comments below I get useful directions on how to implement deque based array. Is there a direction how to implement deque based object using class ?

I get understand some points like I need :

addFront()
removeFront()
peekFront()

addBack()
removeBack()
peekBack()

but I'm confused about some points :

how many pointers I need ? at least I know from queue I need two(head-tail) pointer but not sure if I need more in deque
which data type in javascript convenient in this case as a base? I saw some tutors in youtube talking about circular array for example which unknown for me in JS.

edite2:

I was following a book called: learning javascript data structures and algorithms 3rd edition

in chapter5 of this book the author started to implement Deque based on object only and some variables

but I didn't understand how he did that because the code encrypted but I can still reach to his files from and test his approach github repository

I can say that @trincot answer very close of book author approach

but when I compare the results I get this [1 = author - 2 = @trincot] :

according to the book index taking about linked list comes in chapter6 so I didn't expect his solution will be based on something he didn't mentioned before

plz if I miss any point I will be grateful to tell me it ... thanks

As stated in comments, JavaScript has native support for deque operations via its Array class/prototype: push, pop, shift, unshift.

If you still want to write your own implementation, then you can go for a doubly linked list, where you just need two "pointers". It should be said that in JavaScript we don't really speak of pointers, but of objects. Variables or properties that get an object as value, are in fact references in JavaScript.

Alternatively, you can go for a circular array. Since in JavaScript standard Arrays are not guaranteed to be consecutive arrays as for example is the case in C, you don't really need to use an Array instance for that. A plain object (or Map) will do.

So here are two possible implementations:

QUESTION

Why do I get JavaScript undefined property in Observable but not in HTML?

Asked 2018-Apr-02 at 12:00

I am trying to use Mike Bostock's 'Observable' to re-create a simple HTML webpage, but I am encountering TypeError: Cannot read property 'timeFormat' of undefined in reference to the line of code that draws the chart, namely:

d3.select('#events').data([repositoriesData]).call(chart);

As visible in my notebook, the error points to the .call(chart) parameter.

Can anyone help me why I get this error in Observable when the script works just fine in HTML? And how can I fix it?

As evinced by Alpesh Jikadra comment and jsFiddle (below), the JavaScript function works just fine when embedded in a standard HTML page:

This answer was provided by Tom MacWright in the Observable help forum, where I raised the question after being prompted by Jared Smith:

The event-drops module expects d3 to be just ‘hanging around’ on the window object. This isn’t ideal: modules should really declare their dependencies and load them with AMD, but anyway - it’s not a dealbreaker. I added a cell that sets window.d3 = d3 and that makes event-drops happy. This was the issue that complained about timeFormat - it expected d3.timeFormat to just be there.

[Also] I created a cell for the output, and now reference that in d3.select(events) instead of d3.select('#events'). See the little observer for one explanation of why: cells run the order that they need to depending on each other, so it’s best to connect things like d3.select to elements on the page based on referencing variables, rather than using strings like ‘#events’ to select elements on the page.

QUESTION

Select infos in sub-divs with jQuery

Asked 2017-Mar-12 at 21:02

I am a member of Safaribooksonline.com and I love it.

Now I would like to save a list of the books that I have in my library.

If I look at the html-source of the books list, I have divs like [1] below within the class "main".

I loaded jQuery into the browser console and then selected all "main" divs with books_list = jQuery(".main"). This gives me an Object with entries like Object { 0: , 1: ....

I can iterate over these entries and extract the sub-infos (book title etc).

What is the most idiomatic way to get the sub-divs and sub-infos from these main divs? Ideally in JSON format. So that I have {title: "book title", author: "book author", etc}

[1] Divs containing book infos
