As I’ve gotten more experience working with immutable data structures, I’ve found that they can be beneficial in many ways. However, most programs that interact with the outside world must model state changes somehow. In these cases, I’ve noticed that I still need to be careful about s...
In computing, a persistent data structure or immutable persistance is a data structure that always preserves the previous version of itself when it is modified. Such data structures are effectively immutable, as their operations do not (visibly) update the structure in-place, but instead always yie...
In programming, immutable means a value that cannot be changed once set.Most programs require the generation, modification, and deletion of data. So, why would anyone want to deal with immutable data?In this tutorial, we will look at the immutability of primitives, arrays, and objects using ...
In the last article we learnt how to create an immutable data structure in PHP. There were a few issues to work through, but we got there in the end. Now onto making the immutable class more useful and easier to create modified copies. Note that these are copies and not modifications, ...
ll take a look at how one might implement a general-purpose immutable stack today in C# 3.0. We'll then expand that to immutable queues, trees, etc. (And I might even discusshow one could take advantage of typesafe covariance when designing interfaces for immutable data structures,oh ...
There are several parameters that determine the difficulty of modifying data in Blockchain. We analyze the impact of each of these parameters on the immutability measure of various blockchain structures. We also study the required computational and electrical power as well as the time for a ...
Mutate a copy of data without changing the original source Setup via NPM npm install immutability-helper --save This is a drop-in replacement forreact-addons-update: // import update from 'react-addons-update';importupdatefrom'immutability-helper';conststate1=['x'];conststate2=update(state1...

In "Purely Functional Data Structures", Okasaki discusses solutions to this problem. Anonymous December 10, 2007 Right. I deliberately glossed over that one. If we were really buff then we'd do something like memoize the result of the dequeue so that the cost was only born once -- bu...
in a code editor. Despite the allure of fancy data structures like ropes, my editor is implemented(*) as a view on top of the simplest of all data structures: a giant array of bytes (the contents are strictly ASCII - or occasionally EBCDIC. Yes, it's still around). Inserts, deletes...
