/* strict typing extends to browser API which enables error free code at compile time.*/
// this won't work because querySelector returns type Element
let roomNameEl:HTMLElement = el.querySelector('.room-name')
// this solves the problem
let roomNameEl:Element = el.querySelector('.room-name')

// this will not work cause Element doesn't have value attr
let roomNameEl:Element = el.querySelector('.room-name')
roomNameEl.value // error no such attr
// this will work, also notice typecasting is possible
