Convert array with one giant string of "numbers", seperated by commas, into an array of numbers (not strings)

The current string of numbers is as follows: 

["151,47,47,200,42,130,39,39,152,144,84,66,137,39,83,155,40,49,109,178,91,196,99,190,36,38,169,63,31,60,83,61,79,156,137,64,169,173,40,39,87,188,170,154,188,152,71,106,76,105,184,122,60,71,134,32,39,48,54,77,47,168,134,60,59,161,95,167,108,115,74,132,143,197,99,193,96,174,182,61,48,129,59,190,76,194,197,54,61,72,145,193,70,192,106,164,52,179,179,53"]

Notice that there are double quotes on both ends, which I need to get rid of.

The goal format is:

[151,47,47,200,42,130,39,39,152,144,84,66,137,39,83,155,40,49,109,178,91,196,99,190,36,38,169,63,31,60]....

I've tried using rStrip and replace, but that isn't working. Any ideas?

Thanks!

you've already got what you need, almost. this means it's easier to convert and parse than transform.

a really simple and fast way without looping:

JSON.parse("["+["151,47,47,200,42,130,39,39,152,144,84,66,137,39,83,155,40,49,109,178,91,196,99,190,36,38,169,63,31,60,83,61,79,156,137,64,169,173,40,39,87,188,170,154,188,152,71,106,76,105,184,122,60,71,134,32,39,48,54,77,47,168,134,60,59,161,95,167,108,115,74,132,143,197,99,193,96,174,182,61,48,129,59,190,76,194,197,54,61,72,145,193,70,192,106,164,52,179,179,53"]+"]")

Split, iterate, and cast:

var a = ["151,179,179,53"];
var values = a[0].split(',').map(Number);
console.log(values);

You can use .split() and then iterate through the array, parsing the elements to ints.

DEMO

HTML:

<div id='show'></div>

JS:

var stringArray = "151,47,47,200,42,130,39,39,152,144,84,66,137,39,83,155,40,49,109,178,91,196,99,190,36,38,169,63,31,60,83,61,79,156,137,64,169,173,40,39,87,188,170,154,188,152,71,106,76,105,184,122,60,71,134,32,39,48,54,77,47,168,134,60,59,161,95,167,108,115,74,132,143,197,99,193,96,174,182,61,48,129,59,190,76,194,197,54,61,72,145,193,70,192,106,164,52,179,179,53";
var numArray = stringArray.split(',');
for (var n=0;n<numArray.length;n++) {
    numArray[n] = parseInt(numArray[n],10);
}
//add 1 to each to prove they are ints
for (var n=0;n<numArray.length;n++) {
    document.getElementById('show').innerHTML += numArray[n]+'+1 = '+(numArray[n]+1)+'<br/>';
}

var strings = data[0].split(','); // array of strings containing numbers
var numbers = [];

for (var i = 0; i < strings.length; i++) {
    numbers[i] = parseInt(strings[i],10);
}

Edit: That's exactly what @J148 suggested in his comment
