词法分析顾名思义就是在单词层面对代码进行解释,它主要会将代码字符串划分为一个个独立的单词(token)。 在理解完每个单词的意思后我们会根据英语语法规则划分句子的结构,这个步骤对应的编译原理的概念是语法分析(Syntax Analysis/Parser)。语法分析的过程会将词法分析生成的单词串根据定义的语法规则生成一颗抽象语法树(A...

JavaScript code validation becomes hassle-free with our advanced JS code checker. It scans JavaScript syntax for common bugs, ensuring you can easily find out why your code is not working correctly. It flags both errors and warnings, which must be looked into. For instance, if there are any...

It tries to either back off from doing this or halt with an error when doing it will generate broken JS output, but there are cases where it will fail to recognize the problem and simply generate broken JS without warning. This is much more likely to happen in code that was not explicit...
The problem is not necessarily a syntax error, although it often is. JavaScript Verifier looks at some style conventions as well as structural problems. It does not prove that your program is correct. It just provides another set of eyes to help spot problems. JavaScript syntax checker is ...

IntelliJ IDEA also integrates with JavaScript linters and the Flow type checker. With the built-in debugger, you can debug both your client-side and server-side code and even run JavaScript code snippets in the interactive debugger console. Note that IntelliJ IDEA supports debugging JavaScript ...
