javascript - 如何映射和更改数组内的值？

Question

我对 JavaScript 还很陌生，我想知道如何检查 Angular 色类型的每次迭代并更改值，并根据 Angular 色类型相应地更改它。

array = [
 {
id: "1",
role: "User"
},
{
id: "2",
role : "Provider"
},
{
id: "3",
role: "Administration"
}
]

// If role: User, change to role: "Disable"
// If role: Provider, change role to "Read Me"
// If role Administration, change role to "Admin"

这样的事情应该有效:

let array = [
    {
        id: "1",
        role: "User"
    },
    {
        id: "2",
        role : "Provider"
    },
    {
        id: "3",
        role: "Administration"
    }
];

let roleMappings = {
    User: "Disable",
    Provider: "Read Me",
    Administration: "Admin"
};

let result = array.map( value => {
    value.role = roleMappings[value.role];
    return value;
});
console.log(result);
