Test if a value is a valid typed array length.
To use in Observable,
isTypedArrayLength = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-typed-array-length@umd/browser.js' )To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:
var isTypedArrayLength = require( 'path/to/vendor/umd/assert-is-typed-array-length/index.js' )To include the bundle in a webpage,
<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/assert-is-typed-array-length@umd/browser.js"></script>If no recognized module system is present, access bundle contents via the global scope:
<script type="text/javascript">
(function () {
window.isTypedArrayLength;
})();
</script>Tests if a value is a valid typed array length.
var bool = isTypedArrayLength( 5 );
// returns true
bool = isTypedArrayLength( -1 );
// returns false
bool = isTypedArrayLength( 2.0e200 );
// returns false
bool = isTypedArrayLength( 3.14 );
// returns false
bool = isTypedArrayLength( null );
// returns false- A valid
lengthproperty for a typed array is any integer value on the interval[0, 2^53-1].
