Javascript has many primitive types that make up a program. In fact any language must provide a standard set of primitive values, Javascript is no different. In order to further understand this language we must start with the primitive (basic) values that Javascript offer's. This lecture will cover string, number, boolean, null, undefined and NaN primitive types.

![Deprecated features of PHP7
[DEPRICTAED] Style constructors
PHP 4 style constructors (methods that have the same name as the class they are defined in) are deprecated. PHP 7 will return an E_DEPRECATED please only use the construct() method.
[DEPRICATED] Static calls to non-static methods
Static calls to methods that are not declared static are deprecated, and may be removed in the future.
[DEPRICATED] Password hash
The salt option for the password_hash() function has been deprecated to prevent developers from generating their own (usually insecure) salts. The function itself generates a cryptographically secure salt when no salt is provided by the developer - therefore custom salt generation should not be needed.
[DEPRICATED] Capture session meta data
The capture_session_meta SSL context option has been deprecated. SSL metadata is now available through thestream_get_meta_data() function. Deprecated features of PHP7](https://i.ytimg.com/vi/sioobwq0TAk/mqdefault.jpg)
