Extract the array out of the string

How do I extract the array out of the string?

Current:

"['Biller.Customer.Data@Taxonomy', 'Product.Platform and Enterprise Services Data.Data@Taxonomy']"

Expected:

['Biller.Customer.Data@Taxonomy', 'Product.Platform and Enterprise Services Data.Data@Taxonomy']

I tried using regex and it did nothing:

string.replace(/"/g, '')

Thank you in advance.

It will be better to produce a valid JSON string instead of that format. However, if you're stuck with that because of a factor out of your control, then you can use or write a parser that can handle it (e.g. JSON5):

TS Playground

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-html -->

<script type="module">

import JSON5 from "https://cdn.jsdelivr.net/npm/json5@2.2.3/dist/index.min.mjs";

const input = "['Biller.Customer.Data@Taxonomy', 'Product.Platform and Enterprise Services Data.Data@Taxonomy']";

const array = JSON5.parse(input);

console.log(array); // ["Biller.Customer.Data@Taxonomy", "Product.Platform and Enterprise Services Data.Data@Taxonomy"]

</script>

<!-- end snippet -->

Or, if you understand and accept the dangers of string evaluation, you can also use eval():

TS Playground

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

const input = "['Biller.Customer.Data@Taxonomy', 'Product.Platform and Enterprise Services Data.Data@Taxonomy']";

const array = eval(input);

console.log(array); // ["Biller.Customer.Data@Taxonomy", "Product.Platform and Enterprise Services Data.Data@Taxonomy"]

<!-- end snippet -->

You could use JSON.parse, but note that single quotes are not valid string delimiters in JSON, use replaceAll to change them to double quotes if you are not the one generating the string. If you are in control of the original string, just use double quotes as delimiters instead.

JSON.parse(yourString.replaceAll("'", '"')) could solve your problem, but it is very risky, since if one of your strings had an apostrophe, that would become invalid json, thus JSON.parse would throw an error.

Note: Pay VERY close attention to the single and double quotes in the replaceAll

myarray=(this.stringArray.match(/\'([^,])*\'/g) ||[])
          .map(x=>x.slice(0,-1).slice(1))

EDIT

If you only want to split any string into an array then you can use the following methods depending on your version of TypeScript:

1. [...yourString]
2. yourString.split('separator')
3. Array.from(yourString)

Like in the comments by Gustavo and devjoco described, No1 and No3 would split your string into each characters.
No2 would partially achieve your goal, but you would be stuck with the enclosing brackets and would e.g. need to use it like this:

yourString.split(', ')

So the whitespace after the comma would not end up in the result array.

BUT if you are working with JSON-like strings representing data, then using the approach jsejcksn described would be your best bet.
