The MIN_SAFE_INTEGER constant has a value of -(253 - 1) or -9007199254740991.
It is a non-writable, non-enumerable, and non-configurable property.
"Safe" refers to the ability of JavaScript to represent integers exactly and to correctly compare them.
The syntax to access the MIN_SAFE_INTEGER
constant is:
Number.MIN_SAFE_INTEGER
MIN_SAFE_INTEGER
is accessed using the Number
class name.
Example: Value of Number.MIN_SAFE_INTEGER
value = Number.MIN_SAFE_INTEGER;
console.log(value); // -9007199254740991
value_minus_1 = value - 1;
value_minus_2 = value - 2;
// JS Number cannot exactly represent integers smaller than 'value'
// and correctly compare them
console.log(value_minus_1 == value_minus_2); // true
Output
-9007199254740991 true
Note: If you have to use integers greater than MAX_SAFE_INTEGER, consider using BigInt.
