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
