Native JS Perfect deep copy

Don't talk much , Go straight to the code ：

function deepClone(source) {
    
            let targetObj = source.constructor == Array?[]:{
    };
            for(let keys in source) {
    
                if(source.hasOwnProperty(keys)) {
    
                    if(source[keys] && typeof source[keys]=='object') {
    
                        targetObj[keys] = source[keys].constructor == Array?[]:{
    };
                        targetObj[keys] = deepClone(source[keys]);
                    }else {
    
                        targetObj[keys] = source[keys];
                    }
                }
            }
            return targetObj;
        }
