impact on the interactivity of the page.Context is important when we talk about script parsing and compiling slowly-we're talking about ordinary mobile devices. The average user's phone is configured with a low-provisioned CPU and GPU, possibly due to the memory limitations of the phone, and there is no L2/L3 cache setting.In the JavaScript performance article, I noticed that it took a different time to parse approximately 1M of the extracted script files on low-provisioned phones and high-prov

Minimum spanning tree
Selecting the n-1 edge in a connected graph with n vertices, constituting a minimum connected subgraph, and minimizing the sum of the weights on the n-1 edge of the connected subgraph, it is called the minimum spanning tree of the connected network.
For example, a connected network, as shown in the above figure G4, can have multiple spanning trees with different weights combined.

MINI-VGA is a video interface that is used to replace standard VGA on laptops and other systems. In addition to its tight composition and output VGA video signal, the MINI-VGA port also adds the ability to output AV terminal signals and s-video signals by expanding the display identification data (Extended display identification data).
Today the Mini-dvi interface has replaced MINI-VGA for most applications. Most of the MINI-VGA are used in Apple's Ibook
