How to create a map from a double value array in Javascript

Use the regular Map constructor to transform a 2D key-value Array into a map

const searchDomains: any = new Map([
  [SearchDomain.MY_BOOKMARKS, 'My Bookmarks'],
  [SearchDomain.PUBLIC_BOOKMARKS, 'Public Bookmarks'],
  [SearchDomain.MY_SNIPPETS, 'My Snippets'],
  [SearchDomain.PUBLIC_SNIPPETS, 'Public Snippets']
]);

searchDomains.get(SearchDomain.MY_BOOKMARKS) // returns "My Bookmarks"

Use Array.from() to transform a map into a 2D key-value Array

console.log(Array.from(searchDomains)) // Will show you exactly the same Array as kvArray
