javascript - 枚举返回的 api 数据的索引

Question

我试图通过下面的函数枚举从 api 输出的项目列表。

//函数输出“Prints => Washington Capitals Main.js:52 New York Islanders Main.js:52 Pittsburgh Penguins Main.js:52 Carolina Hurricanes Main.js:52 Columbus Blue Jackets etc”

I want the function to output "Prints => 

Main.js:52 1:New York Islanders
Main.js:52 2:Pittsburgh Penguins
Main.js:52 3:Carolina Hurricanes
Main.js:52 4:Columbus Blue Jackets"



const url2 = ('https://statsapi.web.nhl.com/api/v1/standings');
        const response2 = await (fetch(url2));
        const data2 = await response2.json();
async componentDidMount() {
data2.records.map(function(element){
                element.teamRecords.map(function(element2){
                    const teamNames = element2.team.name;
                    console.log(teamNames)
            });

        });


    }

Prints =>

Main.js:52 Pittsburgh Penguins
Main.js:52 Carolina Hurricanes

您需要在地图功能中提供索引

const url2 = ('https://statsapi.web.nhl.com/api/v1/standings');
        const response2 = await (fetch(url2));
        const data2 = await response2.json();
async componentDidMount() {
data2.records.map(function(element){
                element.teamRecords.map(function(element2, index){
                    const teamNames = element2.team.name;
                    console.log(`${index} : ${teamNames}`)
            });

        });


    }
