Why is the test fuction declaration not found in the window object? Thanks
!function(){
function test(){
console.log("testing");
}
var check = window["test"]
console.log(check); //undefined
}();

Since function test() is local to the scope of the toplevel function expression, it's not bound to window, the global scope. You can refer to it as a local variable:
!function() {
function test() {
console.log('testing')
}
console.log(test)
}()
Or bind it directly to window for a global variable:
!function() {
window.test = function test() {
console.log('testing')
}
var check = window['test']
console.log(check)
}()
You cannot access the local scope as a variable - see this question for more details.
testis not in the window object? You've created a closure, that's kind of the point...
