isSafeInteger(value)

Check if a value is a safe integer primitive.

const lolite = require("lolite.issafeinteger")
const assert = require("node:assert")

assert.ok(lolite.isSafeInteger(42))
assert.ok(lolite.isSafeInteger(Number.MAX_SAFE_INTEGER))
assert.ok(lolite.isSafeInteger(Number.MIN_SAFE_INTEGER))

assert.ok(!lolite.isSafeInteger(Math.pow(2, 53))) // Out of bounds
assert.ok(!lolite.isSafeInteger(3.14))            // Not an integer
assert.ok(!lolite.isSafeInteger(Infinity))        // Not finite
assert.ok(!lolite.isSafeInteger("42"))            // String primitive
assert.ok(!lolite.isSafeInteger(42n))             // BigInt is not a Number primitive
