Javascript 如何将带有另一个数组的数组添加到新数组中？

Question

So my challenge right now is unable to add array with another array into another new array.

my code:

var disabletimerange = { basedonservicetype: "", basedonservicer: "" }
var arr = [{"StartTime":"09:00:00","EndTime":"09:10:00"},{"StartTime":"10:00:00","EndTime":"15:00:00"}]
for (var xx = 0; xx < arr.length; xx++) {
    var bookedStartTime, bookedEndTime
    bookedStartTime = arr[xx].StartTime.slice(0, -3)
    bookedEndTime = arr[xx].EndTime.slice(0, -3)

    if (disabletimerange.basedonservicer === "") {
        var disabletimealreadybookedtiming = "[" + '"' + bookedStartTime + '"' + "," + '"' + bookedEndTime + '"' + "]"
        disabletimerange.basedonservicer = JSON.parse(disabletimealreadybookedtiming)
    } else {
        var disabletimealreadybookedtiming = "[" + '"' + bookedStartTime + '"' + "," + '"' + bookedEndTime + '"' + "]"
        disabletimerange.basedonservicer = "[" + "[" + disabletimerange.basedonservicer + "]" + "," + disabletimealreadybookedtiming + "]"
        disabletimerange.basedonservicer = JSON.parse(disabletimerange.basedonservicer)
}

Uncaught SyntaxError: Unexpected number in JSON at position 3 --> at the last line it cannot parse.

In short, what i want is basically 2 array stick tgt instead of adding into it

var y = ["hi", "123"]
var x = ["yo", "312"]

this
[["hi", "123"], ["yo", "312"]] instead of ["hi", "123", "yo", "312"]

and it must be array. not text form

Answer 1

You can do:

 var y = ["hi", "123"] var x = ["yo", "312"] var result = [x, y] console.log(result)

Answer 2

As you described

How to add array with another array into a new array?

• create a new array

• push your arrays into this new array one by one

 let x = [1,2]; let y = [3.4]; let z = []; z.push(x) z.push(y); console.log(z);
