I am trying to learn typescript but i am not clear on few concepts on typescript such as:
1) I am but not the part
Object = Object.assign
export const htmlElementsMap: Object = Object.assign( {}, homePageElementsMap, loginPageElementsMap, productDetailPageElementsMap, productListPageElementsMap, shoppingBagPageElementsMap, thankYouPageElementsMap );
2) Same with this part
export const UrlNavigationMap: Object = {
What is an object?3) For this function i am not sure what does this
PromiseLike<void>
means:performAs(actor: PerformsTasks): PromiseLike<void> { return actor.attemptsTo( Click.on(homePageElementsMap.lnk_men), SearchItemBySku.called() ); }
4)
export class FillShippingAddress implements Task {}
- What does implements means?and last:
5) What is a
static
and why it is assigned to the class name?export class AddItemsToShoppingBag implements Task{ static called(gender: string): AddItemsToShoppingBag { return new AddItemsToShoppingBag(gender); }
