How to Convert Number to BigInt in JavaScript

To convert a Number to BigInt in JavaScript, you can “use the BigInt() method.”

const numberValue = 1234567890;

const bigIntValue = BigInt(numberValue);




Always be cautious when converting between BigInt and Number, especially when dealing large numbers. Converting a very large BigInt to a Number can result in a loss of precision.

Likewise, converting a non-integer Number to a BigInt will result in an error. Always ensure the number you’re converting fits within the target type’s limits.
