javascript - TypeScript: Creating an empty typed container array -

i creating simple logic game called "three of crime" in typescript.

when trying pre-allocated typed array in typescript, tried this:

var arr = criminal[]; 

which gave error "check format of expression term" .

also tried doing this

var arr : criminal = []; 

and produced "cannot convert any[] 'criminal'

what 'typescript' way this?

the issue of correctly pre-allocating typed array in typescript obscured due array literal syntax, wasn't intuitive first thought.

the correct way be

var arr : criminal[] = []; 

this give correctly typed, empty array stored in variable 'arr'

hope helps others!
