typescript object equality code example

Example 1: Javascript compare two objects

var person1={first_name:"bob"};
var person2 = {first_name:"bob"}; 

//compare the two object
if(JSON.stringify(person1) === JSON.stringify(person2)){
    //objects are the same
}

Example 2: javascript how to compare object values

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;
}
