@ublitzjs/preprocess library for preprocessing code/templates

It has two modules: @ublitzjs/preprocess itself and @ublitzjs/preprocess/render.

The first one exports function "preprocess", which removes any data from any file within two strings including them.

When using "/*!REMOVE*/" and /*!STOP_REMOVE*/ (use set what you need) code transforms from this:

console.log(
    "hello world",
    /*!REMOVE*/ "This is for debug",
    //this is commented functionality /*!STOP_REMOVE*/ "this was commented"
);

To this:

console.log(
    "hello world",
 "this was commented"
)

To implements build script it is enough to:

import {preprocess} from "@ublitzjs/preprocess";
await preprocess("input.js", "output.js", "/*!REMOVE*/", "/*!STOP_REMOVE*/")

When using with esbuild (which bundles code in one "executable") comments must start from "!" and option "legalComments" must be "inline".

The other one - a template engine (more a tokenizer with unique design);

It can handle only interpolation, but in a streaming way + recursive interpolation of templates + multiple interpolations in one place. It is great for generating pages from components. Soon there will be examples (it is more of a framework, so get ready for difficulties)
