Given the code below: Which three code segments result in a correct conversion from number to string? Choose 3 answers

In JavaScript a numeric value can be converted to its string representation by (1) invoking its own Number.prototype.toString() method, (2) calling the built-in String constructor as a function, or (3) forcing implicit coercion through concatenation with an empty string or a template literal.

Option A invokes toString(); option D calls String(numValue); option B uses a template literal (back-ticked ${numValue} ) which interpolates numValue and always returns a string. All three therefore return a correctly-typed string.

C. Number objects have no toText() method; call throws TypeError.

E. (String)numValue is not valid ECMAScript casting syntax; results in SyntaxError at parse time.

14ᵗʰ Ed. (2023)

§21.1.3.29 “Number.prototype.toString” – describes numeric toString conversion.

2. ECMA-262

§19.1.1.1 “The String Constructor Called as a Function” – String(value) returns ToString(value).

3. ECMA-262

§7.1.17 “ToString Abstract Operation” – implicit coercion via concatenation/template literals.

4. ECMA-262

§12.2.9 Template Literals – evaluation always produces a String value.
