Library Methods

CompareProperties

This method compares the properties of two objects. It returns all the different and common properties between the two objects.

Example:

const firstObject = {
    foo: 1,
    bar: 2
};
const secondObject = {
    foo: 2,
};

objectDeepCompare.CompareProperties(firstObject, secondObject);
/*
Will return: 
{
    differences: ['bar'],
    common: ['foo]
}
*/

CompareArrays

This method compares two arrays for equality. It returns true or false.

Example:

const firstArray = [1, 2];
const secondArray = [1, 2];

objectDeepCompare.CompareArrays(firstArray, secondArray);
/*
Will return: true
*/

CompareValuesWithConflicts

This method compares the properties of two objects (deep comparison). It returns an array. Each element in the array is the path of the property that is different.

const firstObject = {
    nested: {
        foo: 1,
        bar: 2
    }
};
const secondObject = {
    nested: {
        foo: 2,
        bar: 4
    }
};

objectDeepCompare.CompareValuesWithConflicts(firstObject, secondObject);
/*
Will return: ['nested.foo', 'nested.bar']
*/
