With BigInts, you can safely store and operate on large integers even beyond the safe integer limit ({{jsxref(\"Number.MAX_SAFE_INTEGER\")}}) for Numbers.\n\nA BigInt is created by appending n to the end of an integer or by calling the BigInt() function.\n\nThis example demonstrates where incrementing the {{jsxref(\"Number.MAX_SAFE_INTEGER\")}} returns the expected result\n\nYou can use most operators to work with BigInts, including +, , -, , and % — the only forbidden one is >>>. A BigInt is not strictly equal to a Number with the same mathematical value, but it is loosely so.\n\nBigInt values are neither always more precise nor always less precise than numbers, since BigInts cannot represent fractional numbers, but can represent big integers more accurately. Neither type entails the other, and they are not mutually substitutable. A {{jsxref(\"TypeError\")}} is thrown if BigInt values are mixed with regular numbers in arithmetic expressions, or if they are implicitly converted to each other.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
