Parameter<\/th>TypeScript Class<\/th>TypeScript Interface<\/th><\/tr><\/thead>
Definition<\/td>TypeScript Class is a template which holds methods,variables and provides a skeleton to object.<\/td>TypeScript Interface is a blueprint which will tell a deriving class what to implement.<\/td><\/tr>
Syntax<\/td>class <className>{
\/\/body
}<\/td>		interface <iName>{
\/\/declarations
}<\/td><\/tr>
Practical Usage<\/td>To design a skeleton of modules functionality wise<\/td>To hide a complexity from external accessing resource and securing core logic<\/td><\/tr>
Instantiable<\/td>We can Instantiate class using its object<\/td>We can not instantiate interface<\/td><\/tr>
Inheritance<\/td>Class supports inheritance by extending other class<\/td>Supports inheritance but can not implement other interfaces<\/td><\/tr>
Functions<\/td>Class can have functions and function has complete definition<\/td>Interface can have function but it can not define it<\/td><\/tr>
Constructor<\/td>Class can have constructor<\/td>NA<\/td><\/tr>
Access Specifiers<\/td>Class can public, private, protected<\/td>Interface uses only public access specifier.<\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"
