When accessing non-local variables, if you expect them to be integers then cast the explicitly with 0| before using them - this will allow the compiler to do fast integer arithmetic with them, rather than using the interpreter's maths routines (which have to cope with doubles and strings)....
Performance - eval() runs the interpreter/compiler. Ifyour code is compiled(如果你的代码是编译型的,那么“使用”eval()会有性能问题), then this is a big hit, because you need to call a possibly-heavy compiler in the middle of run-time. However, JavaScriptis still mostly an interpreted lang...

Interpreted language is to dynamically interpret and execute the program through the interpreter when the program is running, such as Python, JavaScript language. The compilation process of compiled language: the compiler first performs lexical analysis and syntax analysis on the code, generates an ...

As can be seen from the figure, the structure of the AST is very similar to the structure of the code. In fact, you can also regard the AST as a structured representation of the code. The subsequent work of the compiler or interpreter needs to depend on the AST, not the source code...
