How to sort arrays with multiple items - Javascript

Question

What I am trying to do is sort my three arrays (array1, array2, and array3) in order by their 0th term, to display the following.

1, banana, 2, grapes, 3, oranges.

This is my code, but I can't figure out how to get it to sort the way I want.

var array1 = ["1", "banana"];
var array2 = ["3", "oranges"];
var array3 = ["2", "grapes"];
var array4 = [];

function myFunction(){
    array4.push(array1, array2, array3);
    alert((array4).sort(function(a, b){return a-b}));
}

Sort the elements based on [0]th index.

(array4).sort(function(a, b){return a[0]-b[0]})

function myFunction(){
    array4.push(array1, array2, array3);
    alert((array4).sort(function(a, b){return a[0]-b[0]}));
}

Replace Your code with this :

var array1 = ["1", "banana"];
var array2 = ["3", "oranges"];
var array3 = ["2", "grapes"];
var array4 = [];

function myFunction()
{
    array4.push(array1, array2, array3);
    alert(array4.sort());
}

You Output will be 1,banana,2,grapes,3,oranges
