A brief discussion on the memory leak problem caused by js closure_javascript skills

In js closures, "local variables" can be defined, but calling them externally, especially repeated assignment calls, will cause a lot of memory overhead. How to prevent this phenomenon from happening? Are there any similar memory or efficiency issues to be aware of regarding closures? How to avoid it?

Memory problems may be caused by the following reasons:
1. Circular reference causes memory leak
2. Memory leak caused by external function call

Avoid memory leaks

1. Break circular references
2. Add another closure
3. Avoid closure itself
