	// TODO: revisit the following, as using `gfill` is not the most performant, especially for large arrays. We have two options: (1) use a native add-on which delegates to an appropriate C function which performs the loop or (2) use @stdlib/blas/ext/base/(d|s|c|z)fill functions which use native add-ons. The latter option is not great, as we only get perf boosts for large arrays for a select number of dtypes. The former option is more work, as we may need to write a bespoke add-on for handling the argument signature and the various types that `value` can assume (e.g., number, complex, etc). If we had a generic strided `copy` package with an add-on, we could wrap the value as a single element strided array with a stride of `0` and copy from `x` to `y`, and thus would not need to write a bespoke add-on. Note, however, that calling into a native add-on is not free. For shorter arrays, we'll likely observe a perf hit in Node.js. For now, we focus on just getting something working...

Creates a filled array having a specified length.

@param {NonNegativeInteger} length - array length
@param {*} value - fill value
@param {string} [dtype="float64"] - data type
@throws {TypeError} first argument must be a nonnegative integer
@throws {TypeError} third argument must be a recognized data type
@returns {(TypedArray|Array|ComplexArray)} array or typed array

@example
var arr = full( 2, 1.0 );
// returns <Float64Array>[ 1.0, 1.0 ]

@example
var arr = full( 2, 1.0, 'float32' );
// returns <Float32Array>[ 1.0, 1.0 ]
