[es6 feature] first of all default
keyword with export
allows us to set anonymous name we want to set when we import
it.
if you export it with
export const clock
,
then you have to import it strictly(es6 way - using object destructuring syntax for named exports) with
import { clock } from './clock
or also can use import * as clocks from './clock'
if you want to import all constants/variables(i.e. all named exports jammed into one object). this will make clocks
as an object with all exported variables/anything within it.
like
clocks = {
clock : clock \\ import {clock} from './clock',
....
}
named exports are useful to export several values. during the import, it is mandatory to use the same name of the module as it was defined in source file.
but a default export can be imported with any name for example:
export default k = 12; // in file test.js
import m from './test' // note that we got the freedom to use import m instead of import k, because k was default export
console.log(m); // will log 12
score:0
its es6 feature, its just like giving an alias name or assigning one variable reference to another with some other name
behind the curtain it is like this when you import with some other name:
clock_1 = clock
score:1
because you use export default. which means that you export only that class so the name is not that relevant. anyway, that's why tslint(a set of rules) says that it's forbidden to use export default.
