Is there a function that can convert an array ['A', 'B', 'C'] to an object array [{name: 'A'}, {name: 'B'}, {name: 'C'}]?
Or do I need to write a util function? It is no big deal to write one but curious if a well known function is already there.
Thanks
You can use Array.prototype.map(). Array.map is a method that will iterate through each element in an Array and return an output based on the callback. You can find more information on Array.map on the MDN: https://developer.mozilla.org/fr/docs/Web/JavaScript/Reference/Objets_globaux/Array/map
And here is a working example: https://jsbin.com/qawener/edit?js,console
In this example, we take each element of the array and we return an object with {"name": }. This then creates the newArray array that will have [{name: 'A'}, {name: 'B'}, {name: 'C'}].
const originalArray = ["a", "b", "c"];
let newArray = originalArray.map(element => { return {name: element}; });
console.log(newArray);
Map works very well for these types of situations.
const array = ['A', 'B', 'C'];
const myNewArray = array.map(function(map, i) {
const dict = {"name":array[i]}
return dict;
}, {});
console.log(myNewArray)
Beside the given answer, you may use short hand properties for the object.
const
names = ["a", "b", "c"],
result = names.map(name => ({ name }));
console.log(result);
maplike thisarr.map(name => ({name})).
