What is the inherited type for the variable example
in const example = ['Dylan']
?
(1 Point)
- unknown[]
- string
- string[]
- any[]
Solution
To determine the inherited type of the variable example
in the statement const example = ['Dylan']
, we need to analyze the declaration.
-
The structure of the variable: The variable
example
is declared usingconst
, indicating that its reference cannot change after the initial assignment. It is initialized with an array containing a single string element,'Dylan'
. -
Type inference: In TypeScript, when you create an array with a specific data type, TypeScript infers the type of the array based on the contents. Since
'Dylan'
is a string, TypeScript infers the type ofexample
to be an array of strings. -
Conclusion on types: The options provided are:
unknown[]
string
string[]
any[]
Given the analysis, the correct type for example
is string[]
, which means it is an array of strings.
Final Answer
string[]
