ecmascript 6 - Is "type" a keyword in JavaScript? -

-

i came across using "type" in a piece of es6 code. 

export type action =   {     type: 'todo/complete',     id: string,   } |   {     type: 'todo/create',     text: string,   } |   {     type: 'todo/destroy',     id: string,   } |   {     type: 'todo/destroy-completed',   } |   {     type: 'todo/toggle-complete-all',   } |   {     type: 'todo/undo-complete',     id: string,   } |   {     type: 'todo/update-text',     id: string,     text: string,   };

couldn't find sheds light on it. keyword? do?

as mentioned pitaj, type symbol here not part of es6, rather part of flow static type checker.

here docs type symbol.

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
