lets say we have :
let array_of_objects = [
{
"color": "purple",
"type": "minivan",
"id": this.object.index // i know this is not valid code,but can this somehow get its own index within the array as value ?
},
{
"color": "red",
"type": "station wagon",
"id": this.object.index //this should be 1
}
]
Actual question in code comments.. what i'm trying to do is to fill a form's inputs using an object,and i want to be able to display the actual index of the object within the array in one of the inputs
instead of using index as id I suggest create a complex id or you can use uuid() library for creating unique user id uuid npm
import { v4 as uuidv4 } from 'uuid';
array_of_objects = array_of_objects.map((item, index) => ({ id: uuidv4(), ...item}))
console.log(array_of_objects);
let array_of_objects = [
{
"color": "purple",
"type": "minivan"
},
{
"color": "red",
"type": "station wagon"
}
];
array_of_objects = array_of_objects.map((item, index) => ({ id: index, ...item}))
console.log(array_of_objects);Just initialize the array without the id and add it afterwards using a for loop.
let array_of_objects = [
{
"color": "purple",
"type": "minivan",
},
{
"color": "red",
"type": "station wagon",
}
]
for (let i = 0; i < array_of_objects.length; i++) {
array_of_objects[i].id = i;
}
