FAQs about JS Type Conversion
Type conversion is the process of changing a value from one data type to another.
There are two types: Explicit (manual) and Implicit (automatic).
Use Number(), parseInt(), or the unary + operator.
The number is converted to a string, and the result is concatenation.
Truthy values evaluate to true in a boolean context, while falsy values (e.g., 0, "", null, undefined, NaN) evaluate to false.
== performs type coercion, while === checks both value and type.
It helps prevent unexpected behavior in your code and ensures compatibility across operations.
