JavaScript Fun Question: Find the Murderer
A key witness was murdered. Before he died, he tried to name the murderer, but his voice was weak and intermittent, making it difficult to distinguish.
We obtained his recording, represented by a string. This string starts with a letter, and each "~" symbol represents an uncertain letter.
The length of the string does not mean the length of the name, because he may die before saying the murderer's full name.
The police provided a list of suspects and asked you to help find the murderer based on the recording.
The result should be a string. If not found, return an empty string. If multiple are found, please return these and separate them with commas.
var suspects=['Bernard Deltheil','Peter Gone','Peter Reeves','Roland Scorsini'] sc('b~~~~~~~~~~~~~~l',suspects); //'Bernard Deltheil' sc('p~t~r',suspects); //'Peter Gone,Peter Reeves' sc('a~b~c~~d',suspects); //''
Note:
1. Match each suspect’s name, ignoring case.
2. The code should be as short as possible
For the following implementation, I used regular expressions to first replace the "~" symbol within the string with ".", and then use it as Part of the pattern, matched with the name.
function sc(s,a){
var r = [];
a.forEach((e)=>{if(new RegExp("^" + s.replace(/~/g,"."),"i").test(e))r.push(e);});
return r.join(",");
}
The above are fun JavaScript questions to find out the murderer. For more related content, please pay attention to the PHP Chinese website (www.php.cn)!

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.

JavaScript Engines: Comparing Implementations
Apr 13, 2025 am 12:05 AM
Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.
