What is the typescript equivalent of python isinstance

step1Choices: string[] = ['a', 'b'];

In python i can check isinstance(step1Choices, list) How can i do the same in typescript ?

When i do console.log(typeof step1Choices) I get object

What i am looking for is to find out whether it is a list of strings or a dictionary(dictionary in python. Even though it is initialised as list, later i change it to dict)

But you already know that `step1Choices` is a `string[]`? – RoadRunner Jan 02 '19 at 04:53
At a later stage i change it to another type. – Sandeep Balagopal Jan 02 '19 at 04:54
You can just use `instanceof`. – RoadRunner Jan 02 '19 at 05:01
