javascript - 使用另一个数组的值修改 javascript forEach 结果

Question

我想用另一个数组的值修改以下 forEach 结果，但我无法让它工作。

const BbDescriptionDictionary = ['AAA' , 'BBB', 'CCC',] 
const boardBasisOptionsModified = [];  

this.boardBasisOptions.forEach( (value) => {
    boardBasisOptionsModified.push({ 
        "key": value, "value": BbDescriptionDictionary[value] 
    });  
});

this.boardBasisOptions = boardBasisOptionsModified;

Answer 1

可以给.forEach第二个参数，表示boardBasisOptions的索引。像这样:

this.boardBasisOptions.forEach( (value, index) => {
    boardBasisOptionsModified.push({ 
        "key": value, "value": BbDescriptionDictionary[index] 
    });  
});
