high-promise v1.0.2

High Promise

This is a wrapper for the native es6 promise to make the Promise syntax a bit nicer.

How to use high-promise

// import high-promise
const highPromise = require('high-promise');

const multiplyVal = highPromise((resolve, reject, x) => resolve(x * x));
  
const fs = require('fs');
const readFile = highPromise((resolve, reject, path) => 
    fs.readFile(path, 'utf-8', (err, data) => resolve(data)));
    
// Same use
multiplyVal(3).then(console.log) // 9
readFile('path.txt').then(console.log) // path.txt content

highPromise has to receive a function with (resolve, reject) as the first two parameters, additional paramteres are added later like this (resolve, reject, x, y, z)

Before high-promise

const multiplyVal = x => 
  new Promise(resolve, reject) => resolve(x * x);
  
const fs = require('fs');

const readFile = path => 
  new Promise(resolve, reject) => 
    fs.readFile(path, 'utf-8', (err, data) => resolve(data))
    
 multiplyVal(3).then(console.log) // 9
 readFile('path.txt').then(console.log) // path.txt content

Notice the constant new Promise which is nested inside a function, it's necessary to wrap the promise because it's evaluated instantly without any way to pass extra variables into it.
