Works for any data type, but really intended for array comparison.
The algorithm:
function isMatch(item1, item2) {
if (item1 === item2) return true;
if (isArray(item1) && isArray(item2) && (item1.length === item2.length)) {
for (let i = 0, length = item1.length; i < length; ++i) {
if (not(isMatch( item1[i], item2[i] ))) return false;
}
return true;
}
else return false;
}
isMatch([], []); // true
isMatch(['a', 'b'], ['a', 'b']); // true
isMatch(['a', 'b'], ['a', 'b', 'c']); // false
// Elements must be in matching order to match:
isMatch(['a', 'b', 'c'], ['c', 'b', 'a']); // false
isMatch([1, 2, [3]], [1, 2, [3]]); // true
let obj = {prop: 1};
isMatch([obj], [{prop:1}]); // false
let obj2 = obj;
isMatch([obj], [obj2]); // true
// Behaves the same as === operator for primitive types and non-array objects:
isMatch('', ''); // true
isMatch('0', '0'); // true
isMatch('0', 0); // false
isMatch('00', '01'); // false
isMatch(Infinity, Infinity); // true
isMatch(undefined, undefined); // true
let obj = {prop: 1};
isMatch(obj, {prop:1}); // false
let obj2 = obj;
isMatch(obj, obj2); // truenpm i @writetome51/is-match
import {isMatch} from '@writetome51/is-match';
