Why should the method name here be replaced by an array? Is there any good?

like the following, I saw it by a plug-in in ps. After decryption, I found that it was like this, and I could understand it, but I didn"t quite understand it. Why did I write it this way? More efficient execution?

Is this probably the reason for

?
javascript and hash table

(also guessed. In other words, the Adobe script itself is a deep pit.)


this is the function of the compressor / cipher.
you take a look at Baidu js online encryption , basically, take out all the api names and put them together, and then call them in an array.
after all, a.b.c (d) is the same as a ['b'] ['c'] (d) in js.

a.b.c(d)
// 
var apiArr = ['b', 'c']
a[apiArr[0]][apiArr[1]](d)

A more powerful one will also encode all the strings in this apiArr. The goal of
may be to complicate the logic and prevent others from reading your code.
js is the kind of source code that can be seen directly by right-clicking on the web page, so do it a little bit to prevent the gentleman but not the villain.

ps:, you see, his variable name 0x9527 is written like a memory pointer, but it's all a bluff.
