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 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 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 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
