we can see
function generate() {
this.a = 'hello';
}
obj = new generate();
so, my question is, how to understand ‘this.’ phenomenon?

Yes, functions are objects.
But there is more to it than that in your sample code. If you call a function with the
newkeyword JavaScript creates a new object for you and then uses the function as the constructor: within the functionthisreferences the newly created object, and the new object will be returned – but this new object is not the function itself: to oversimplify, if your function isgenerate()then the new object is based ongenerate.prototype, which by default is an empty object.Further reading: https://developer.mozilla.org/en/Introduction_to_Object-Oriented_JavaScript
