[Roadmap] WelsonJS-Lite and LOL(Living off the land)

[Namhyeon, Go]

The design of WelsonJS is based on LOL(Living off the land). However, many separate binary files have been added to accommodate the needs of many customers.

We may need a Lite version of the WelsonJS. It will consist only of JS files, like the early version of the WelsonJS.
