1. JavaScript vs TypeScript Types

Notes :

• 1-6 are Primitive Data Types
• All primitives are immutable. A primitive is not an object and has no methods of its own.
• Null is special primitive
• All types in TypeScript are subtypes of a single top type called the Any type.

Exercises :

• [ ] Evaluate all JavaScript Types
• [ ] undefined vs null vs not defined
• [ ] Cons & Pros Dynamic Type

2. Typescript Types

How to declare typescript type :

• Type inference ( implicit ) let ti = "hello"
• Type annotations ( explicit ) let ta:string = "hello ts"

Exercises :

• [ ] Convert all JavaScript Types to TypeScript
• [ ] Function Type
• [ ] Union Type |
• [ ] Type Aliases
• [ ] Setup Environtment ( eslint, prettier )

3. Array & Tuples

Tuples is an array with fixed size and known data types.

There are few ways to declare an array:

1. Using Type Inference let list = [1, 2, 3, 4];
2. Using square brackets. elementType[] let fruits: string[] = ['Apple', 'Orange', 'Banana'];
3. Using a generic array type. Array<elementType> let fruits: Array<string> = ['Apple', 'Orange', 'Banana'];

Exercises :

• [ ] Array of Number
• [ ] Array of String
• [ ] Array with Union
• [ ] Tuple
• [ ] Array of Object
• [ ] Array multidimensional
• [ ] Destructuring

4. Object

Object is a type that represents the non-primitive type, i.e. anything that is not number, string, boolean, bigint, symbol, null, or undefined

Exercises :

• [ ] Object Literal
• [ ] Nested Object
• [ ] Nested, Object of Array
• [ ] Nested, Object of Object ( Dynamic Properties)
• [ ] Destructuring
• [ ] Utility Types ( ReadOnly, Record )

5. Functions

Functions are the building blocks of readable, maintainable, and reusable code. A function is a set of statements to perform a specific task. Functions organize the program into logical blocks of code.

Exercises :

• [ ] function basic : declaration,expression, arrow
• [ ] optional & default parameters
• [ ] rest parameter
• [ ] conditional type with union, generic, overloads

6. Classes

• [ ] class basic : constructor, properties, method
• [ ] access modifiers (private, public, private)
• [ ] inheritance / sub-class
• [ ] static member
• [ ] abstract classes

7. Interface vs Type

8. Advanced Type

• [ ] Partial Partial<T>
• [ ] Required Required<T>
• [ ] Readonly Readonly<T>
• [ ] Pick Pick<T, K>
• [ ] Omit Omit<T, K>
• [ ] Record Record<K,T>
• [ ] Extract Extract<T, U>
• [ ] Exclude Exclude<T,U>
