flowtype - Indexable signature not found in object literal in Flow -


i have interface:

interface iformdata {     [string]: string };  export type { iformdata };

it's simple interface accepts key-value string. when use this, 

const formdata:iformdata = { email: '...', password: '...' };

it gives me error:

[flow] property $key of iformdata (indexable signature not found in object literal)

i tried this, gives me same error:

var formdata: iformdata;    // error formdata['email'] = ...; formdata['password'] = ...;

i searched on google 2 days, still stuck in here , need help!

any advice appreciate it.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
