Article Introduction：Core points Commonly used object merging methods in JavaScript include the expansion operator (...) and the Object.assign() method. The expand operator is more modern and concise, while the Object.assign() is more compatible and suitable for older environments. Both the expansion operator and Object.assign() perform a shallow copy when merging objects, meaning that the nested object is still a reference to the original object. Modifying nested objects in merged objects may affect the original object, resulting in potential unexpected side effects. For deep merging (correctly merging nested objects), libraries like custom functions or Lodash can be used. A custom function is provided in the article

Article Introduction：Pure CSS creates engaging typewriter text effects Core points: CSS typewriter effects make website content more dynamic and attractive by gradually displaying text, and can be used for login pages, personal websites and code demonstrations. Typewriter effects can be created by using the CSS steps() function to change the width of the text element from 0% to 100%, and animation simulation of the cursor of "photo" the text. Typing effects can be adjusted by increasing or decreasing the number of steps and duration of the typing animation to accommodate longer or shorter text. Typewriter effects can be used in conjunction with flashing cursor animations to enhance the effect, and the cursor can be customized by adjusting its border-right attribute, color, flashing frequency, and more.

Article Introduction：io.Reader and io.Writer are the core interfaces for handling I/O operations in Go. 1.io.Reader is used to read bytes from data sources, and commonly used implementations include files, buffers and network connections; 2.io.Writer is used to write bytes to targets, such as files, buffers or network connections; 3. Both are often used in conjunction with each other, such as data replication through io.Copy; 4. The standard library provides a variety of packaging tools, such as buffered read and write, restricted read size and multiplexing, etc., to improve flexibility and performance. Mastering them can effectively deal with various I/O scenarios.

Article Introduction：Effectscope is used in Vue3 to structure management of responsive side effects, you can clean up uniformly by creating an effectScope instance and using scope.run(). It is suitable for scenarios such as building custom combination functions, managing dynamic functional modules and developing plug-ins, and is especially suitable for situations where side effects life cycles need to be manually controlled. When using it, be careful that stop() must be called explicitly to clean it up, and the responsive logic of the built-in components has been automatically managed by Vue without additional wrapping. In addition, scopes can be nested, and all child scopes will stop when the parent scope stops.

Article Introduction：In Java8, Predicate is used for conditional judgment, accepting parameters and returning boolean values, which are often used to filter data, such as filtering elements that meet the conditions in combination with filter() method; it can encapsulate complex logic and support combination operations of and(), or(), and negate(). Consumer is used to perform operations without return values. It is commonly used when forEach traversing the collection, such as printing or logging; it supports multiple operations in sequence through andThen() chain call. It should avoid too many side effects when using it. It is recommended to use references to improve the simplicity of the code and combine it with StreamAPI to play a greater role.

Article Introduction：map is a common method for array processing in JavaScript, which generates new arrays by applying functions to each element. When used, provide a function as a parameter. The function receives three parameters: the current element, the index and the original array, and the most commonly used is the current element. For example, constdoubled=numbers.map(num=>num*2); multiply each number in the array by 2. Common uses include: 1. Convert data formats such as extracting user names; 2. Modify DOM elements collections such as obtaining text contents of all elements; 3. Render React lists such as generating JSX elements. Notes include: Do not perform side effects operations in map; write return when using normal functions

Article Introduction：The JavaReflection API allows you to check and operate components such as classes, methods, fields at runtime, so that the code has dynamic adaptability. It can be used to discover class structures, access private fields, call methods dynamically, and create instances of unknown classes. It is commonly found in frameworks such as Spring and Hibernate, and is also used in scenarios such as serialization libraries, testing tools, and plug-in systems. 1. The dependency injection framework realizes automatic assembly through reflection; 2. The serialization library uses reflection to read object fields to generate JSON; 3. The test tool uses reflection to call the test method and generates a proxy; 4. The plug-in system dynamically loads and executes external classes with the help of reflection. However, it is necessary to pay attention to performance overhead, security restrictions, packaging damage and lack of security during compilation period, and should be used with caution to avoid
