Extract the array represented as a string

Question

i have a string as below and i would like to extract the array between the quotes.

mystring = "['str1','str2']"

I tried it with eval and i do not want to use eval in my code. is there any other neat way to do this ?

Yes. this is not a valid JSON and i dont want to use eval either. — boredbear153, Sep 15 '21 at 09:13
@boredbear153 is the data in the string always an array of strings? — evolutionxbox, Sep 15 '21 at 09:16
See [Parsing string as JSON with single quotes?](/q/36038454/4642212). — Sebastian Simon, Sep 15 '21 at 09:17
@evolutionxbox sometimes it can be integers as well. like "[5,6]" — boredbear153, Sep 15 '21 at 09:18
@SebastianSimon This is working.. Replace the single quote into double quotes and then parsing it.. thank you. — boredbear153, Sep 15 '21 at 09:22

function parseString(string) {
  return string
    .split(",")
    .map((str) => str.replace("[", "").replace("]", "").replaceAll("'", ""));
}

This assumes none of array indexes includes character ",".

this works as expected. i will also get the input as "[5,6]". In this case, the expected output is [5,6]. However, with the above function it is ["5","6"]. Do i have to transform it again checking if each element is a number or string ? – boredbear153 Sep 15 '21 at 09:17
@boredbear153 Why not simply request valid JSON instead? Either use JSON or build your own custom parser. – Sebastian Simon Sep 15 '21 at 09:18
@boredbear153, Yes, I think you need to do that. Also, I think there are quite a few other things that should be considered. Will be a complicated function in the end. – Erfan Sep 15 '21 at 09:22
@Erfan Yes. i m considering the answer from the below link https://stackoverflow.com/questions/36038454/parsing-string-as-json-with-single-quotes – boredbear153 Sep 15 '21 at 09:23

@SebastianSimon I will request to provide valid JSOn. Not sure if it is possible in this case, based on the outcome, i need to decide my next step. – boredbear153 Sep 15 '21 at 09:24
