practice, eval is rarely used, but perhaps you've seen someone use eval to get objects that are difficult to index. One of the problems with the Document Object Model (DOM) is that sometimes it is painful to get the object you ask for. For example, here's a function that asks the user which image to transform: Which image you want to transform-you can use the following function: function Swapone () { var the_image = prompt ("Change parrot

The_evaled_answer to eval ("2 + 3"), JavaScript will understand and return the 2 and 3 and back to The_evaled_answer.This seems a bit silly, actually can make very interesting things. Using eval, for example, you can create functions directly from the user's input.This allows the program to change itself depending on time or user input, and with extrapolate, you can get amazing results.In practice, eval is seldom used, but you may have seen someone use eval to get objects that are difficult to

Perl5 enables perl5 to use modules in other languages, or when calling Perl from other languages, you have to deal with xs, read its documentation, and understand Bottom-layer details, of course, some tools such as swig can help you a lot, but it is not a long journey after all. This is one of the reasons for the small number of third-party Perl extensions, At that time, perlnet (a plug-in integrating Perl and. net), which was popular with ActiveState, had no final problem.
