How change the value in "active" (true to "Yes" /false to "No").

[ { "id":81, "time":"2022-01-01 19:30:00", "subList":[ { "active":false, "success":null } ] }, { "id":89, "time":"2022-01-01 21:00:15", "subList":[ { "active":true, "success":1 } ] } ]

CodePudding user response：

Array.map

Use Array.map or any other looping to loop through the elements of an array.

You can use ? and : Conditional ternary Operator to shorten a simple if else block.

const list = [ { "id":81, "time":"2022-01-01 19:30:00", "subList":[ { "active":false, "success":null } ] }, { "id":89, "time":"2022-01-01 21:00:15", "subList":[ { "active":true, "success":1 } ] } ];

const newList = list.map(item => {
    item.subList.map(subItem => {
        subItem.active = subItem.active ? "Yes" : "No"
        return subItem;
    })
    return item;
})

console.log(newList)
