배열 연습문제

 

const check_list = [ true, false, false, true, false ];
console.log( "before --> " + check_list );

for ( let i=0; i<check_list.length; i++ ) {
    check_list[i]? check_list[i]=false : check_list[i]=true;
}

console.log( "after --> " + check_list );

 

훨씬 심플한 코드 ▼ ▼ ▼

for ( let i=0; i<check_list.length; i++ ) {
    check_list[i] = !check_list[i];
}
