What is better for static messages in Typescript? (performance and memory wise) -

what better static messages in typescript? (performance , memory wise) variables or methods? let's need hundreds of them. msg1 or msg2()

import {messages} './messages';  export class messagesen implements messages {   readonly msg1 = 'message one';   msg2(): string {    return 'hello second!';  } 

}

from point of encapsulation, fields (aka msg1) must not visible client, need let client work code methods manipulate data of objects , change objects state.

from point of performance accessing field bit faster, because goes , tries find field , returns it. method same thing , goes , call it: 1 operation. in cases functions doesn't change it's context, inlined, allows them accessed faster. if change in function after code execution, compiler can't not optimize , work slower field access.

from point of memory wise, method take more memory stack field

you can see jsperf property access more faster method access.
