將 compose 與多個函數和內部 function 與參數一起使用

Question

我有以下內容：

 { reseller: filterOutNonUsable(dedupe(extractArrVals(data.locks.entries, 'reseller'))) }

調用所有這些函數並為 extractArrVals function 使用第二個參數的最佳方法是什么（請參閱我的示例），以便我可以使用https://www.30secondsofcode.org/snippet/compose ？

Answer 1

const compose = (...fns) => fns.reduce((f, g) => (...args) => f(g(...args)));

const extractArrVals = (obj, key) => {
  /////YOUR FUNCTION
};

const dedupe = (data) => {
  /////YOUR FUNCTION
}

const filterOutNonUsable = (data) => {
  /////YOUR FUNCTION
}

// transformer or whatever it's name
const transformer = compose(
  filterOutNonUsable,
  dedupe,
  extractArrVals
);

transformer(data.locks.entries, 'reseller')
