The following points can be seen:1. No function is defined when quote is used.When you use function, you define a function, -lambda-.When quote is used, (alert k) is run as a table.3. When using function, alert and k are two separate strings.Conclusion: when using quote, lambda is not compiled into a function. With function, a lambda is compiled into a function that can be optimized quickly.The so-called optimization is that you can access the function entrance address quickly and directly, without looking up the address corresponding to the function name and then calling it.
