Function identical

Check if 2 arrays have the same elements in the same order. Strict equality (===) is used to compare elements.

Time complexity: O(n)

Space complexity: O(1)

Example

const a = [1, 2, 3];
const b = [1, 2, 3];

identical(a, b); // true
Copy

Check if 2 Sets have the same elements. Strict equality (===) is used to compare elements.

Time complexity: O(n)

Space complexity: O(1)

Example

const a = new Set([1, 2, 3]);
const b = new Set([3, 2, 1]);

identical(a, b); // true
Copy

Check if 2 Maps have the same key-value pairs. Strict equality (===) is used to compare values.

Time complexity: O(n)

Space complexity: O(1)

Example

const a = new Map([['a', 1]]);
const b = new Map([['a', 1]]);

identical(a, b); // true
Copy
