Converting a string into an array in Typescript?

Question

I'm using Angular 4 and a Spring service that I throws an exception with the message being the toString of a List of messages. The problem is that when I receive the exception response and extract the message, instead of being treated like an Array of strings, it's treated as a single string in the format of: "[message 1, message 2]"

Is there a way in typescript to easily convert this String into an array of strings? I tried instantiating a new Array with the string like: new Array(errorResponse.error.message); but that didn't really work.

message.substring(1, message.length()-1).split(","); should give array of strings — Jason White

It should working for you:

var messages = message.substring(1, message.length-1).split(", ");

Fiddle with a function, which doing this is available here.

It works with JSON.Parse("[message 1, message 2]");
