[Node] JavaScript 객체

Object vs Array

var members = ['sein', 'main88', 'happy'];   //Arryay
console.log(members[1]); // main88 출력

var roles = {             //Object 객체
    'programmer':'sein',
    'designer':'main88',
    'manager':'happy'
}
console.log(roles.designer);  //main88 출력

members Arryay이고 roles는 Object 객체 소스 이다

 

 

Arryay 활용한 반복문(while) 

var members = ['sein', 'main88', 'happy'];   //Arryay
console.log(members[1]); // main88 출력

var i = 0;
while (i < members.length) {
	console.log('array loop', members[i]);
	i = i + 1;
}

 

Object 활용한 반복문(for)

var roles = {             //Object 객체
    'programmer':'sein',
    'designer':'main88',
    'manager':'happy'
}
console.log(roles.designer);  //main88 출력

for (var name in roles) {
	console.log('object =>', name, 'value => ', roles[name]);
}
