JS - Array，只推送某些值

Question

有数组A。必须过滤掉存储在数组B中的某些值。结果应存储在数组C中。

JS

var a = [ 1,2,3,4,5,6];

var b = [ 2,4,6];

var c = []; // shall contain all values of a except the ones from b

这是我的方法：

for (var i = 0; i < a.length; i++){ 
  if(b.indexOf(a[i]) === -1){
    c.push(a[i]);
  }
}

Answer 1

循环a并查看b

for (var i = 0; i < a.length; i++) {
    if (b.indexOf(a[i]) === -1) c.push(a[i]);
}
