Implement a recursion function that accept two number parameters,
"start" and "end".
Then add up all the numbers between "start" and "end".
Can not invoke functions inside itself, all functions that used in
calculation should be anonymous.
For example:
var abc = function(){
// can not invoke "abc"
var result = (function(){})();
}
"start" and "end".
Then add up all the numbers between "start" and "end".
Can not invoke functions inside itself, all functions that used in
calculation should be anonymous.
For example:
var abc = function(){
// can not invoke "abc"
var result = (function(){})();
}
===== Chinese Version =====
实现一个匿名函数, 接受两个数字参数, "start" 和 "end", 把 "start" 到 "end" 之间的数 (包括自身) 相加.
不允许在函数内部调用自己, 参与运算的函数均为匿名函数:
var abc = function(){
// 不能直接调用 "abc"
var result = (function(){})();
}

Good!
I think we can talk about OOP in js next week.
Start from context and bind, anonymous functions and so on!

What the "context" and "bind" means?
"this" keyword inside function?
"event binding"?
"this" keyword inside function?
"event binding"?
