What are is-property's main functionalities?
Check if a string is a valid property name
This feature allows you to check if a given string is a valid JavaScript property name. The first example returns true because 'validPropertyName' is a valid property name, while the second example returns false because '123invalid' is not.
const isProperty = require('is-property');
console.log(isProperty('validPropertyName')); // true
console.log(isProperty('123invalid')); // false
