javascript - TypeScript: Using function parameter as JSON-key name -

-

following situation:

setflags(data:any, key:string) {     this.flags.key= data; }

assumed data {'foo': 'is cool'} , key 'bar' , flags should like:

{     'bar': {'foo': 'is cool'} }

is there simple solution purpose?

edit: reply questions in comments: going typescriptclass used service, stores flags.

@injectable() export class formstoreservice {     flags:any = {};     constructor() {}     setflags(data:any, key:string) {         this.flags.key = data;     } }

when write foo.bar, setting property named bar. if name of property dynamic, should use foo[bar] syntax. setflags method becomes

setflags(data:any, key:string) {  this.flags[key] = data; }
