Package Exports

@stdlib/assert-is-bigint

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/assert-is-bigint) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isBigInt

Test if a value is a BigInt.

Installation

npm install @stdlib/assert-is-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
