Test if a value is an empty string.
npm install @stdlib/assert-is-empty-stringWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Test if a value is an empty string.
``bash`
npm install @stdlib/assert-is-empty-string
`javascript`
var isEmptyString = require( '@stdlib/assert-is-empty-string' );
#### isEmptyString( value )
Tests if a value is an empty string.
`javascript
var bool = isEmptyString( '' );
// returns true
bool = isEmptyString( new String( '' ) );
// returns true
`
#### isEmptyString.isPrimitive( value )
Tests if a value is an empty primitive string.
`javascript
var bool = isEmptyString.isPrimitive( '' );
// returns true
bool = isEmptyString.isPrimitive( new String( '' ) );
// returns false
`
#### isEmptyString.isObject( value )
Tests if a value is an empty String object.
`javascript
var bool = isEmptyString.isObject( '' );
// returns false
bool = isEmptyString.isObject( new String( '' ) );
// returns true
`
`javascript
var isEmptyString = require( '@stdlib/assert-is-empty-string' );
var bool = isEmptyString( '' );
// returns true
bool = isEmptyString( new String( '' ) );
// returns true
bool = isEmptyString( 'beep' );
// returns false
bool = isEmptyString( 0 );
// returns false
bool = isEmptyString( null );
// returns false
bool = isEmptyString( void 0 );
// returns false
bool = isEmptyString( {} );
// returns false
bool = isEmptyString( [] );
// returns false
bool = isEmptyString( function empty() {} );
// returns false
