I am unable to understand Number.isSafeInteger method

It shows false in this code:
0.5 isn’t a very high number and also not a very low number. It is close to zero. But why it shows false?

A Integer is a number that isn’t decimal (and only 32bit large in JS i think, but this can vary from language to language). 1 is a integer, 6 is a integer. 0.5 is not.

You should always try to solve problems yourself and find out what you are working with.

further down in this article you will be told what a integer is.

yes, 0.5 is not an integer

you can read about it in the MDN docs:
