1)Could anyone explain where exactly we use client side functions like g_form and g_user. ?

g_form :

GlideForm.js is the Javascript class used to customize forms.

g_form is a global object in the GlideForm class.

GlideForm.js and g_form are only used on the client (for instance, the web browser).

These methods are used to make custom changes to the form view of records. All validation of examples was done using Client Scripts.

Some of these methods can also be used in other client scripts (such as Catalog Client Scripts or Wizard Client Scripts), but must first be tested to determine whether they will work as expected.

g_user :

g_user is a global object in GlideUser (the Javascript class).  

g_user

• can   only be used in Client Scripts.
• contains name and role information about the current user.
• is typically used in Client Scripts and UI Policies but is also found in UI Actions which run on the client.
• cannot be used in Business Rules or UI Actions which run on the server.
• avoids the need for much slower user queries (for example, GlideRecord queries to get user information)

Session information about the current user and current user roles is contained in the client (for example, web browser). All methods below [except getClientData()] access the session information that is available by default. getClientData() requires setup on the server and use of putClientData() to make session information available.

2)what is exactly difference between g_user.hasRole , g_user.hasRoles() , , g_user.hasRoleExactly() ,and in which scenarios we use these methods ?

g_user.hasRole() :

True if the current user has the role specified, false otherwise. ALWAYS returns true if the user has the 'admin' role.

ex: g_user.hasRole('itil')

g_user.hasRoles()

True if the current user has at least one role specified, false otherwise.

ex: g_user.hasRoles('itil','admin')

g_user.hasRoleExactly()

True if the current user has the exact role specified, false otherwise, regardless of 'admin' role.

ex:g_user.hasRoleExactly('itil');
