Typescript as

// The 'as' keyword asserts that a variable has a type.						=>
// TypeScript throws an error if these types have no overlap.

// The following example will work with jQuery.

let inputElt = $("#text_input");
// type of inputElt is JQuery<HTMLElement>

let inputValue = inputElt.val();
// type of inputValue is string | string[] | null | undefined

// If we are sure that the input element is a valid element and is only
// present once, the value must be of type string.

// Thus we can assert it is a string, as so:
let inputValueAsString = inputValue as string;
