How to replace certain substrings in an array?

Question

I have my data set in a normal data model format:

var data = "Billing, alpha, beta"

But I want to modify this data by formatting the array by replacing "," with "/text/i"

var newData = [/Billing/i , /alpha/i, /beta/i]

Here is the code I have tried:

var data   = "Billing, alpha, beta"
var y = x.split(',')
var newData  = y.replace(",", "/i,")
console.log(newData)

This might work if you remove `y` and just run the `replace` on `data`. — Sam A. Horvath-Hunt, Jul 19 '17 at 09:33
@WiktorStribiżew the output contains space on from second string onwards — Saurabh Raman, Jul 19 '17 at 09:38
@SaurabhRaman Just `trim()` each item, see [update](https://jsfiddle.net/v2g1a72a/2/). Or [split with `,` and space](https://jsfiddle.net/v2g1a72a/4/). — Wiktor Stribiżew, Jul 19 '17 at 09:44

Try this snippet

var data   = "Billing, alpha, beta";
var y = data.split(',');
newData=[];
for(i=0;i<y.length;i++)
  newData.push(new RegExp( y[i].replace(/(^\s+|\s+$)/g,""),"i"));
console.log(newData);

@SaurabhRaman Please accept my solution if you are satisfied – Joey Pinto Jul 19 '17 at 09:45
The output is an array of strings, while OP needs an array of RegExp objects. – Wiktor Stribiżew Jul 19 '17 at 09:47
I appreciate your knowledge many thanks for your help....but there is little correction the output should also not contain ' " ' (double quotes)..... it should look like .... [/Billing/i,/alpha/i,/beta/i] – Saurabh Raman Jul 19 '17 at 09:49
See my edit I've used Regex objects – Joey Pinto Jul 19 '17 at 09:54
