My goal is to include custom properties in the Quasar framework, but I am encountering an error with ESLint. It displays the following message:
Array prototype is read only, properties should not be addedI am looking to implement an extend method for Arrays:
Array.prototype.extend = function (other_array) {
/* A test should be included to verify whether other_array is truly an array */
other_array.forEach(function(v) {this.push(v)}, this)
}
When you modify an object, its behavior changes.
It's okay to alter the behavior of an object for your own code. However, if you change something that is also utilized by other code, there is a risk of causing potential issues.
You have the option to create a function and import it:
helpers.js
let update = function(other_array) {
return other_array.forEach(function(v) {this.push(v)}, this)
}
export default update;
componentA.vue
import update from './helpers.js';
// use update as a regular function
Alternatively, we can utilize native JavaScript methods:
// concatenate two arrays together
firstArray.concat(secondArray);
// or using new ECMA script (spread operator)
finalArray = [...firstArray, ...secondArray];
