TypeTags .get

Overview#

The .get method allows us to lookup the type tag of an object by its type or retrieve its type tag. Behind the curtains, all it does is to call Object.prototype.toString over any value and return the result.

Usage#

TypeTags.get(name | value)#

• Returns the type tag a named type. If it can't find by its name, it will return the value's type tag.

import { TypeTags } from 'typetags'

TypeTags.get('Array')
// → [object Array]

TypeTags.get('Tuple')
// → [object String]

TypeTags.get([])
// → [object Array]

We could use it to get the type tags of a list of type names.

import { TypeTags } from 'typetags'

const list = ['Map', 'String', 'Boolean']
const tags = list.map((type) => TypeTags.get(type))

console.log(tags)
// → [ '[object Map]', '[object String]', '[object Boolean]' ]

Signature#

get(name: Types | NestedTypes): Tags
get(value: any): Tags
