adj.不变的，不可改变的

The codebase is designed to be immutable, meaning once a function is created, its behavior cannot be changed.
代码库被设计为不可变的，意味着一旦创建了一个函数，其行为就不能更改。
In functional programming, an immutable data structure ensures that its contents never change, which enhances code predictability.
在函数式编程中，不可变数据结构确保其内容永远不会改变，这提高了代码的可预测性。
An immutable object in Java is one whose state cannot be modified after it's been created, preventing unexpected side effects.
在Java中，不可变对象是指创建后状态不能修改的对象，避免了意外的副作用。
The database schema is immutable, allowing for efficient caching and synchronization across multiple servers.
数据库模式是不可变的，这使得跨多台服务器的缓存和同步更为高效。
In JavaScript, immutability is a key concept in libraries like Redux, where actions must produce new data structures instead of modifying existing ones.
在JavaScript中，Redux等库中的不变性是一个关键概念，操作必须产生新的数据结构，而不是修改现有结构。
An immutable configuration file ensures that developers always work with the same settings, reducing errors and making deployments more reliable.
不可变的配置文件保证开发者始终使用相同的设置，减少了错误，并使部署更可靠。
In Git, using immutable snapshots of files helps track changes and revert to previous versions if needed, maintaining a clean version history.
在Git中，使用文件的不可变快照有助于跟踪更改，并在需要时回滚到之前的版本，保持清晰的版本历史。
A hash table is often implemented as an immutable data structure, as it allows for efficient lookups without worrying about concurrent modifications.
哈希表常常以不可变数据结构实现，因为它允许高效的查找，而不必担心并发修改。
The design pattern encourages developers to create immutable classes, promoting thread safety and simplifying debugging.
这种设计模式鼓励开发者创建不可变类，促进线程安全并简化调试过程。
In cryptography, some algorithms rely on the concept of immutability to ensure the integrity of encrypted data, as altering the input would result in a different output.
在密码学中，一些算法依赖于不可变性来确保加密数据的完整性，因为更改输入会导致不同的输出。
