const keyword. An initializer for a constant is required; that is, you must specify its value in the same statement in which it's declared (which makes sense, given that it can't be changed later).

const COLUMNS; // SyntaxError: missing = in const declaration
Fixing the error

Adding a constant value
Specify the constant value in the same statement in which it's declared:
const COLUMNS = 80;
