But as a JavaScript developer, you would know this theory doesn't hold long after you start working with dates for real. On top of different date-time formats, you have to consider timezone and ...
Next, this value is rounded to nearest Number type value. Boolean If one of the operands is a Boolean, the Boolean operand is converted to 1 if it is true, or to 0 if it is false. Object If an object is compared with a number or string, JavaScript attempts to return the default value for the object.
This is also used on the return value, in this case to ensure that the result of adding 1 to i will be an integer (as otherwise it could become too large), and to mark the return type of the function. These conversions are required by asm.js, so that an optimising compiler can produce highly efficient native code ahead-of-time.
In Go, a type assertion can be used to access a concrete type value from an interface value. It is a safe assertion that it will panic (in the case of one return value), or return a zero value (if two return values are used), if the value is not of that concrete type. [12]

Magic numbers become particularly confusing when the same number is used for different purposes in one section of code. It is easier to alter the value of the number, as it is not duplicated. Changing the value of a magic number is error-prone, because the same value is often used several times in different places within a program. [6]
A record is a value that contains other values, typically in fixed number and sequence and typically indexed by names. The elements of records are usually called fields or members. An object contains a number of data fields, like a record, and also offers a number of subroutines for accessing or modifying them, called methods.
