The JavaScript Number.MAX_SAFE_INTEGER is a constant number that represents the minimum safe integer. This constant has a value of (253 – 1). Here safe refers to the ability to represent integers and to compare them.


Example: 


Number.MAX_SAFE_INTEGER + 1 === Number.MAX_SAFE_INTEGER + 2


The above expression will evaluate to true which is actually mathematically NOT correct.




Syntax:


Number.MAX_SAFE_INTEGER



Return Value: A constant number.


Example 1: Below example illustrates the usage of Number.MAX_SAFE_INTEGER











                                    filter_none




                                    edit

                                    close




                                    play_arrow




                                    link

                                    brightness_4
