With for loop:
使用 for 循环:
var Array1=[1,2,3,4,5,6];
var Array2=[7,8,9,10,11,12];
for (var i = 0; i < Array1.length; i++){
Array1[i] = Array2[i]
}
console.log(Array1)

in this example, it is possible to exclude the value of an array of type CONST, and the value of an array is passed to or another. I had this problem.
在这个例子中,可以排除类型为 CONST 的数组的值,并将数组的值传递给或另一个。我有这个问题。
fields = [1,2,3,4]
var t = fields.filter(n => {
return n != 4;
});
// t => [1,2,3]
fields.splice(0, fields.length, ...t);
console.log(fields);//[1,2,3]
