isBigInt

Test if a value is a BigInt.

Usage

var isBigInt = require( '@stdlib/assert/is-bigint' );

isBigInt( value )

Tests if a value is a BigInt.

var Object = require( '@stdlib/object/ctor' ); var BigInt = require( '@stdlib/bigint/ctor' ); var bool = isBigInt( BigInt( '1' ) ); // returns true bool = isBigInt( Object( BigInt( '1' ) ) ); // returns true

isBigInt.isPrimitive( value )

Tests if a value is a primitive BigInt.

var Object = require( '@stdlib/object/ctor' ); var BigInt = require( '@stdlib/bigint/ctor' ); var bool = isBigInt.isPrimitive( BigInt( '1' ) ); // returns true bool = isBigInt.isPrimitive( Object( BigInt( '1' ) ) ); // returns false

isBigInt.isObject( value )

Tests if a value is a BigInt object.

var Object = require( '@stdlib/object/ctor' ); var BigInt = require( '@stdlib/bigint/ctor' ); var bool = isBigInt.isObject( BigInt( '1' ) ); // returns false bool = isBigInt.isObject( Object( BigInt( '1' ) ) ); // returns true

Examples

var hasBigIntSupport = require( '@stdlib/assert/has-bigint-support' ); var BigInt = require( '@stdlib/bigint/ctor' ); var isBigInt = require( '@stdlib/assert/is-bigint' ); var bool; if ( hasBigIntSupport() ) { bool = isBigInt( BigInt( '1' ) ); // returns true } else { console.log( 'Environment does not support BigInts.' ); } bool = isBigInt( 1 ); // returns false bool = isBigInt( '1' ); // returns false bool = isBigInt( {} ); // returns false bool = isBigInt( [] ); // returns false bool = isBigInt( null ); // returns false bool = isBigInt( void 0 ); // returns false bool = isBigInt( true ); // returns false bool = isBigInt( function foo() {} ); // returns false
