* @name sample
* @type {Function}
* @param {ArrayLike} x - array-like object from which to sample
* @param {Options} [options] - function options
* @param {NonNegativeInteger} [options.size] - sample size
* @param {ProbabilityArray} [options.probs] - element probabilities
* @param {boolean} [options.replace=true] - boolean indicating whether to sample with replacement
* @throws {TypeError} first argument must be array-like
* @throws {TypeError} options argument must be an object
* @throws {TypeError} must provide valid options
* @throws {RangeError} `size` option must be less than or equal to the length of `x` when the `replace` option is `false`
* @returns {Array} sample

* @example
* var out = sample( [ 3, null, NaN, 'abc', function(){} ] );
