Seq is lazy immutable sequence of data, meaning it will perform as few operations as possible to do its task while skipping creation of intermediate copies. Seq was built to be used this way. Inside Todo component use get or getIn to get the props. Simple enough right? Well, what I ...
A map is like a JavaScript object. It's a keyed collection, meaning that the same types of keys that you would use with JavaScript objects also work with maps. Immutable.js maps are also like native JavaScript Map instances in that they can use anything as a key—not just strings:...
The in-app browser is specifically designed for single sign-on (SSO) purposes, making it a much more secure option. This browser runs on a separate process from the hosting game, meaning the game cannot access it, modify any content, or inject malicious code. On the other hand, when it...
Reverse Indexing of Tuples in Python Much similar to regular indexing, here, we use the index inside the square brackets to access the elements, with only one difference, that is, we use the index in a reverse manner. Meaning, the indexing of the elements would start from the last eleme...
In practice it's used to allow for a single instance of an entity to be stored in one place, with any other uses of it referring back to the original. It's implemented as a State type using State.create, meaning that a reference is just another Immutable.Map of a specific shape. A...
JavaScript uses a reference assignment, meaning that the new object simply refers to the original object, changing the new will also affect the old: foo={a:1};bar=foo;bar.a=2;foo.a// 2 Although this can save memory, when the application is complex, it can result in the state not be...
In the English language, the term "mutable" refers to the ability to change or be modified, while "immutable" denotes the opposite, meaning something that cannot be changed. When we talk about an "immutable object," we are referring to an object whose state or properties remain fixed and ...
Although the two words themselves are close in meaning, their responsibilities in programs are different and they are sometimes incompatible.The immutability concept of D is represented by the const and immutable keywords. Although the two words themselves are close in meaning, their responsibilities ...
In a blockchain, data written to a block are immutable, meaning it cannot be changed. Through cryptographic hash functions and consensus algorithms, each block has a unique hash value, and only the majority of participating nodes agree to write it into the chain. Any change in the block will...
Constraints and/or definitions, such as the way in which data and transactions written to the cryptographically secured ledger are represented in the database table, how they interact relative to other objects in the cryptographically secured ledger, and/or the semantic meaning of any given row, ...
