Today I think of an important improvement to virtual DOM: You can use higher-order functions to pre-evaluate diff and patch, which avoids running time to diff and patch the view, so performance is greatly optimized

It's like calculus.

The differential function is the first order function of the original function

Taiji Live 2014/12/14 9:35:49
View is the initial state continuous based on diff application Patch, that is, integral
Taiji Live 2014/12/14 9:36:49
The view function is restored by seeking the differential and then integrating the first.

It's so, I don't know how it's going to happen

First let the view function be slightly
Taiji Live 2014/12/14 9:47:14
such as constant function, linear function
Taiji Live 2014/12/14 9:48:14
The differential of the combined function of these functions is then asked
9:48:48
Taiji Live 2014/12/14 9:48:48
Like If,for,repeat.
Taiji Live 2014/12/14 9:50:34
If you can't pre-evaluate it, you're fallback to the way it is.

Taiji Live 2014/12/14 9:51:22
You can also leverage the caching mechanism
Taiji Live 2014/12/14 9:53:06
The differential of the constant function is 0, and the patch is the empty operation
9:55:31
Taiji Live 2014/12/14 9:55:31
{{x}} is equivalent to a linear function, the patch is to add the difference, the actual operation with the new value update is possible
9:57:14
Taiji Live 2014/12/14 9:57:14
If the test value is not changed, the patch is empty, otherwise the existing branch is replaced with another branch
Taiji Live 2014/12/14 9:58:40
Repeat is based on the model value of the increase and deletion
