Alright.
if you know the key value, in your case 4 to 10 you can go like this
If you don't know the key values, it's more tricky as you don't have unique element values.
But it should be something like this.
should return arrays (in that case just one) [4,2,3,4,2,5]
So all in all

Code:
function array_between(a,b,c){
var backs=new Array();
for(var i=(a+1); i<b; i++){
backs.push(c[i]);
}
return backs;
}
console.log(array_between(3,10,arr));If you don't know the key values, it's more tricky as you don't have unique element values.
But it should be something like this.
Code:
function findBetweenValues(a,b,c){
var found=0;
var s=false; var e=false;
var backarrays=new Array();
for(var i=0; i<c.length; i++){
if(c[i]==a && found<1){s=i; found=1; }else if(c[i]==b && found==1){e=i; found=0; backarrays.push(array_between(s,e,c)); }
}
return backarrays;
}
console.log(findBetweenValues(5,6,arr));should return arrays (in that case just one) [4,2,3,4,2,5]

console.log(findBetweenValues(5,6,arr));Edit fiddle - JSFiddle - Code Playground

Doing it in 3 steps
Code:
<!DOCTYPE html>
<html>
<head>
<title>Extract an Array from an Array</title>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
</head>
<body>
<p id="demo"></p>
<script>
var myArray = [2,4,3,5,4,2,3, 4, 2, 5, 6,3,7,9];
myArray.splice(0, myArray.indexOf(5)+1);
myArray.splice(myArray.indexOf(6));
document.getElementById('demo').innerHTML = myArray;
</script>
</body>
</html>
