我的三元代码无法使用Javascript
我的三元代码无法使用Javascript
提问于 2020-12-25 02:35:24
我转换成三元的内容：
arr= ["A","T","T","G","C"]
const result = arr.reduce((acc, current)=>{
if(current === "A"){
acc+= "T"
} else if(current === "T"){
acc+= "A"
} else if(current === "G"){
acc+= "C"
} else if( current === "C"){
acc+= "G"
}
return acc
},"")
console.log(result)这就是我如何将它转换成三进制的，但它不起作用，它的给出未定义：
const result = arr.reduce((acc, current)=>{
current === "A"? acc+= "T"
: current === "T"? acc+="A"
: current === "G"? acc+="C"
: current === "C"? acc+= "G"
: acc
},"")回答 1

你没有在你的三元reduce示例中返回结果。
您应该执行以下操作：
const res2 = arr.reduce((acc, current)=>{
return current === "A"? acc+= "T"
: current === "T"? acc+="A"
: current === "G"? acc+="C"
: current === "C"? acc+= "G"
: acc
},"")您也可以去掉括号，只需执行以下操作：
const res2 = arr.reduce(
(acc, current)=>
current === "A"? acc+= "T"
: current === "T"? acc+="A"
: current === "G"? acc+="C"
: current === "C"? acc+= "G"
: acc
,"")页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
