I am working with an array that has properties embedded within it. I am wondering if there is a method to separate out these properties from the array data and transform them into a distinct object containing only the properties?
To exclude all numeric keys from an object, you can use filtering techniques.
let obj = [1,2,3,4];
obj.x = 2;
obj.y = 3;
obj.z = 'test';
const result = Object.fromEntries(Object.entries(obj).filter(([key])=>isNaN(key)));
console.log(result);If you want to retrieve all the keys from an array, you can use the following command: Object.keys(arrayName);
To specifically extract the keys that are not numerical and create a separate object containing these keys along with their corresponding values, you can utilize the code snippet below:
let nonNumericalKeys = {};
let keysFromArray = Object.keys(arrayName);
for (let i = 0; i < keysFromArray.length; i++) {
if(isNaN(keysFromArray[i]) === true) {
nonNumericalKeys['i'] = arrayName[i];
}
}
You will now have an object named nonNumericalKeys which stores all properties of the array referenced as arrayName, excluding any numerical properties.
