who to check if to object is equal code example

Example 1: javascript check if objects are equal

const isEqual = (...objects) => objects.every(obj => JSON.stringify(obj) === JSON.stringify(objects[0]));

// Examples
isEqual({ foo: 'bar' }, { foo: 'bar' });    // true
isEqual({ foo: 'bar' }, { bar: 'foo' });    // false

Example 2: check if objects are equal javascript

function isEquivalent(a, b) {
    // Create arrays of property names
    var aProps = Object.getOwnPropertyNames(a);
    var bProps = Object.getOwnPropertyNames(b);

    // If number of properties is different,
    // objects are not equivalent
    if (aProps.length != bProps.length) {
        return false;
    }

    for (var i = 0; i < aProps.length; i++) {
        var propName = aProps[i];

        // If values of same property are not equal,
        // objects are not equivalent
        if (a[propName] !== b[propName]) {
            return false;
        }
    }

    // If we made it this far, objects
    // are considered equivalent
    return true;
}

// Outputs: true
console.log(isEquivalent(bobaFett, jangoFett));
