scala test is of type in typescript

To test if a value is of a certain type in TypeScript, you can use the typeof operator. However, when using Scala with TypeScript, you will need to use a library like scala-js to interact with TypeScript types. Here's an example of how you can test if an object is of a certain type using scala-js.

import typings.`type-detect`.mod.`type`

val value = "hello world"

if(`type`(value) == "string") {
  println("The value is a string!")
} else {
  println("The value is not a string.")
}
187 chars
10 lines

In the code above, we're using the type-detect library to check the type of the value variable. If it's a string, we print a message saying that it's a string. If not, we print a message saying that it's not a string.

Note that you'll need to install the type-detect library with npm before you can use it in your Scala project.
