@since 3.0.0

@param {object} source - The object to retrieve the value from.
@param {string} key - The name of the property to retrieve from the object. If a property is nested, the names of its preceding properties should be separated by a dot (`.`).
@param {number} min - The minimum value which can be returned.
@param {number} max - The maximum value which can be returned.
@param {number} defaultValue - The value to return if the property doesn't exist. It's also constrained to the given bounds.

@return {number} The clamped value from the `source` object.
