How to use the devextreme/core/utils/common.equalByValue function in devextreme

private _checkObjectsFields(checkingFromObject: Object, checkingToObject: Object) {
        for (let field in checkingFromObject) {
            let oldValue = this._toComparable(checkingFromObject[field]);
            let newValue = this._toComparable(checkingToObject[field]);
            let isEqualObjects = false;

            if (typeof oldValue === 'object' && typeof newValue === 'object') {
                isEqualObjects = commonUtils.equalByValue(oldValue, newValue);
            }
            if (oldValue !== newValue && !isEqualObjects) {
                return true;
            }
        }
    }
