In the following code, why test
function's second this
points to obj
, whereas the first this
points to window
object?
In particular, how can I guess the value of this
by looking at a piece of code?
var test = function(){
console.log('first', this)
return function(){
console.log('second', this)
}
}
var obj = {
a: 1,
b: test()
}
obj.b() // execute function
