Class Context

a signal context class is required to create and register signals. without it, signals won't be able to communicate with each other, and it would not be possible to build a signals dependency graph.

Example

const ctx = new Context() // create signal context
const createState = ctx.addClass(StateSignal_Factory) // feed the state signal factory function to get a signal generator
const createMemo = ctx.addClass(MemoSignal_Factory) // feed the memo signal factory function to get a signal generator

const [idNum, getNum, setNum] = createState<number>(0)
const [idNum2, getNum2] = createMemo((memo_id) => {
    const num2 = getNum(memo_id) ** 2
    console.log("recomputing number squared:", num2)
    return num2
}, { defer: false })

setNum(2) // console.log: "recomputing number squared: 4"
setNum(4) // console.log: "recomputing number squared: 16"
