Description

Import

Terminal

Node.js

const LockedArray = require("@protagonists/locked-array");

---

Example

Code:

// Imports
const LockedArray = require("@protagonists/locked-array");
// Create LockedArray instance
const fruits = new LockedArray(["apple", "orange"]);

// Add "tomato" in the array
fruits.add("tomato");
// Lock the array
fruits.lock();

// Log the array's value
console.log(fruits.value);
// try to add element to the direct value
fruits.value.push("banana");
// Log the array's value
console.log(fruits.value);

Output:

[ 'apple', 'orange', 'tomato' ]
[ 'apple', 'orange', 'tomato' ]
