Test if a value is a semantic version string.
npm install @stdlib/assert-is-semverWe 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 a [semantic version][semantic-version] string.
``bash`
npm install @stdlib/assert-is-semver
`javascript`
var isSemVer = require( '@stdlib/assert-is-semver' );
#### isSemVer( value )
Tests if a value is a [semantic version][semantic-version] string.
`javascript
var bool = isSemVer( '0.0.2' );
// returns true
bool = isSemVer( 'foo' );
// returns false
`
`javascript
var isSemVer = require( '@stdlib/assert-is-semver' );
var bool = isSemVer( '1.0.0' );
// returns true
bool = isSemVer( '1.0.0-alpha.1' );
// returns true
bool = isSemVer( '0.1' );
// returns false
bool = isSemVer( null );
// returns false
