Returns the element associated with a specified index.

@private
@param {ndarrayLike} target - target object
@param {string} property - index string
@param {Object} ctx - context object
@param {Function} ctx.getter - accessor for retrieving array elements
@param {boolean} ctx.strict - boolean indicating whether to enforce strict bounds checking
@param {Function} ctx.postGetArray - function to process a retrieved ndarray
@throws {RangeError} index exceeds ndarray bounds
@returns {(ndarrayLike|void)} result
