let [string1, string2]: string[] = [];

breaking it down:

• on the left the whole [string1, string2] is declared as string[], implying string1, string2 is of type string

• on right hand the empty array is [undefined, undefined, undefined, ...] when destructuring string1 and string2 gets assigned to undefined
• finally string1, string2 are of type string with value undefined
