TypeTags .enhance

Overview

The .enhance method wraps a built-in type into a TType object which provides us methods for introspection.

Usage

TypeTags.enhance(name)
  • Returns an enhanced TType object with extended methods.
import { TypeTags } from 'typetags'


const ArrayType = TypeTags.enhance('Array')


ArrayType.isConstructor()
// → true


ArrayType.instance(1, 2, 3)
// → [1, 2, 3]

We could use it to check if a built-in is available on our runtime.

import { TypeTags } from 'typetags'


let encoder = TypeTags.enhance('TextEncoder')


if (encoder.isAvailable()) {
  encoder.instance().encode('hey!')
}

For a list of all available methods, check out the TType API reference.
