Partial Function Builder
部分函数生成器是一个简单的实用程序，它允许使用对象解构将部分参数应用于其命名参数的函数。
注意
此实用程序仅支持 -直到现在- 向原始函数接受的一个参数 提供命名 部分参数. 您可以检查 lodash 的
partial以将部分参数应用于位置参数。有关详细信息，请参阅用法。
Installation
npm i @abdelrahman-elkady/partial-function-builder
Usage
Simple Usage
const { toPartialBuilder } = require('@abdelrahman-elkady/partial-function-builder');
const addAndMultiply = ({ n1, n2, n3 }) => (n1 + n2) * n3;
const addPartialBuilder = toPartialBuilder(addAndMultiply);
const multiplyWithThree = addPartialBuilder({ n3: 3 });
multiplyWithThree({ n1: 1, n2: 1 }); // 6 .. expression evaluated is (1 + 1) * 3
Composition
const { toPartialBuilder } = require('@abdelrahman-elkady/partial-function-builder');
const add = ({ n1, n2, n3 }) => n1 + n2 + n3;
const addPBuilder = toPartialBuilder(add);
const partialOne = addPBuilder({ n1: 5 })
partialOne({ n2: 2, n3: 3 }); // 10
// Create a partial builder for the partial function `partialOne`
const partialOnePBuilder = toPartialBuilder(partialOne);
const partialTwo = partialOnePBuilder({ n2: 3 });
partialTwo({ n3: 1 }); // 9
Overriding
const { toPartialBuilder } = require('@abdelrahman-elkady/partial-function-builder');
const add = ({ n1, n2, n3 }) => n1 + n2 + n3;
const addPBuilder = toPartialBuilder(add);
const partialOne = addPBuilder({ n1: 5 })
partialOne({ n2: 2, n3: 3, n1: 10 }); // 15

Partial Function Builder
Partial function builder is a simple utility that allows having functions with partially applied arguments to their named arguments using object destructuring.
Note
This utility only supports -till now- supplying named partial arguments to one single argument that the original function accepts. You can check lodash's
partialto apply partial arguments to positional arguments.See usage for more details.
