to find out the maximum and minimum value of a number you should write as well as like this...

here as you can see that i have took a nn variable & assigned its value. but you will get two different number of MAX_VALUE of 45.45 & MAX_SAFE_INTEGER 45.45.
when you write the code you will get its MAX_VALUE is 1.7976931348623157e+308.

and MAX_SAFE_INTEGER is 9007199254740991.

its happened because MAX_VALUE & MAX_SAFE_INTEGER isn't same.thats why its return different type of data.

as well as you will get also the same for MIN_VALUE & MIN_SAFE_INTEGER.

var nn = Number(45.45)

console.log(Number.parseInt(nn))

console.log(Number.MAX_VALUE)

console.log(Number.MIN_VALUE)

console.log(Number.MIN_SAFE_INTEGER)

console.log(Number.MAX_SAFE_INTEGER)
