Apa tipe paksaan dalam javascript

Type Coercion refers to the process of automatic or implicit conversion of
values from one data type to another. This includes conversion from 
Number to String, String to Number, Boolean to Number etc. when different types
of operators are applied to the values.

In case the behavior of the implicit conversion is not sure, the constructors
of a data type can be used to convert any value to that datatype,
like the Number(), String() or Boolean() constructor.

1. String to Number Conversion: When any string or non-string value is added to
a string, it always converts the non-string value to a string implicitly.
When the string ‘Rahul’ is added to the number 10 then JavaScript does not give
an error. It converts the number 10 to string ’10’ using coercion and then
concatenates both the strings.

2. String to Number Conversion: When an operation like subtraction (-),
multiplication (*), division (/) or modulus (%) is performed,
all the values that are not number are converted into the number data type,
as these operations can be performed between numbers only.

3. Boolean to Number: When a Boolean is added to a Number, the Boolean value is
converted to a number as it is safer and easier to convert Boolean values to
Number values. A Boolean value can be represented as 0 for ‘false’ or 1 for
‘true’. 

4. The Equality Operator: The equality operator (==) can be used to compare
values irrespective of their type. This is done by coercing a non-number data
type to a number.
