Another modern ECMAScript method that has good modern browser support across the board is the Object.fromEntries() method, which is similar to the Array.from() method that you are more likely to be familiar with.
Object.fromEntries() allows you to create an object from an array of key-value pairs. It takes an array of entries, where each entry is an array itself containing two elements: the key and the corresponding value.
Below is a simple example to illustrate how the method works:
|
const myEntries = [
['name', 'Fran'],
['age', 35],
['home', 'Saturn']
];
const userProfile = Object.fromEntries(myEntries);
console.log(userProfile);
/*
{
"name": "Fran",
"age": 35,
"home": "Saturn"
}
*/
|
In this example, I have an array called myEntries that has three key-value pairs. When I pass this array to Object.fromEntries(), it transforms it into an object based on the values the array contains. The resulting userProfile object is shown in the comment at the bottom of the code snippet above.
The above example uses multiple nested arrays, which is a good format for use with Object.fromEntries(). The method automatically picks up the arrays as key/value pairs to drop into the resulting object.
You can also use a combination of Object.fromEntries(), and Array.map() to convert a single array of objects to a single useful object. For example:
|
const data = [
{ rank: 1, name: 'Sampras' },
{ rank: 2, name: 'Agassi' },
{ rank: 3, name: 'McEnroe' }
];
const newData = Object.fromEntries(
data.map(item => [item.rank, item.name])
);
console.log(newData);
/*
{
"1": "Sampras",
"2": "Agassi",
"3": "McEnroe"
}
*/
|
In this example, I have an array of objects called data, and I want to create a new object where the keys are the "rank" values of each object, and the values are the "name" values. The resulting newData object is again shown in the comment at the bottom of the snippet.
Some final notes about this method:
- If a nested array or object has more than two values, only the first two are used for the key/value pair, the rest are ignored.
- If non-string values are used, they're automatically converted to strings since the resulting object expects only strings.
- The array passed into the method must be iterable
You can try out the above code examples in this CodePen demo. I've also included a few extra examples that address a few of the quirks and limitations of the method as mentioned in the bullet list above.
