javascript - Can't get some JS syntax -


this question has answer here:

file.js:

(function(m) {     //some     //code     //here }(m))

i can't construction mean?

that code defines function inline , executes it.

think substituting function variable:

(function(m) {     //some     //code     //here }(m))

then that's same as:

var f = function(m) {     //some     //code     //here } (f(x))

but without having define f.
