    DEJAVU CALL

    Intercepts a function call and stores the result with the given context. In calls that have the same parameters, it will return the stored result. The proposal is to reduce the response time for processing heavy functions, but it always has the same result. Doing this in a simple and transparent way, taking away the need for developer memory management. Can store multiple functions and their contexts separately in an individual stack of items limit 20, each new surplus item will erase an older one.

    GET FAST!! - Reduced in test case from 107 milliseconds to 12 milliseconds

    Thanks for npm~lucasmreis

    IMPORTANT!!!

    In 'recall' your function (named as Service) will receive yours parameters (named as context) using the spread operator

    export const recall = (contextId, Service, context, Throw = false) => {
      /*  *** */
      return Service(...context)
    }

    To intercept and return result from memorizer or run your function, depending on being memorized earlier

    Example:

    const { recall, getHash } = require('dejavu-call')
    /* IMPORTANT!!! in 'recall' your function (named as Service) will receive yours parameters (named as context) using the spread operator */
       export const recall = (contextId, Service, context, Throw = false) => {
        ***
        return Service(...context)
      }
    /* */
     
    const heavyFunctions = (a, b, c) => a ++c
    const functionId = getHash('heavyFunctions') || getHash(heavyFunctions.toString())
    const heavyFunctionsMemorized = context => recall(functionId, heavyFunctions, context)
     
    const context = [a, b, c]
    const result = heavyFunctionsMemorized(context)

    OR

    Example:

    const { recall, getHash } = require('dejavu-call')
     
    const heavyFunctions = (a, b, c) => a ++c
    const functionId = getHash('heavyFunctions') || getHash(heavyFunctions.toString())
     
    const context = [a, b, c]
    const result = recall(functionId, heavyFunctions, context)

    If you do not want to use memorizer as an interceptor, you can use this way

    Example:

    const { getHash, remember } = require('dejavu-call')
     
    const heavyFunctions = (a, b, c) => a ++c
    const functionId = getHash('heavyFunctions') || getHash(heavyFunctions.toString())
     
    const context = [a, b, c]
    let result
    try {
      result = remember(functionId, context)
    } catch (err) {
      /* err = dejavu-call: no memory found || dejavu-call: no keeper found */
      result = functionId(...context)
    }
