1. Define variable to store your name as a string.

2. Define constant to store your birth year as a number.

3. Prepare function to print greeting with single argument.

4. Call function passing value as literal.

5. Call function passing variable.

6. Call function passing constant.

1. Print all odd numbers from the range [15, 30] including endpoints.

2. Implement function `range(start: number, end: number)` doing the same task.

1. Implement function `average` with signature

`average(a: number, b: number): number` calculating average (arithmetic mean).

2. Implement function `square` with signature

`square(x: number): number` calculating square of x.

3. Implement function `cube` with signature

`cube(x: number): number` calculating cube of x.

4. Call functions `square` and `cube` in loop, then pass their results to

function `average`. Print what `average` returns.

1. Define constant object with single field `name`.

2. Define variable object with single field `name`.

3. Try to change field `name` and assign other object to both identifiers.

Explain script behaviour.

4. Implement function `createUser` with signature

`createUser(name: string, city: string): object`. Example:

`createUser('Marcus Aurelius', 'Roma')` will return object

1. Define array of objects with two fields: `name` and `phone` (phone book).

Example: `{ name: 'Marcus Aurelius', phone: '+380445554433' }`.

2. Implement function `findPhoneByName` with signature

`findPhoneByName(name: string): string`. Returning phone from that object

where field `name` equals argument `name`. Use `for` loop for this search.

1. Define hash with `key` contains `name` (from previous example) and `value`

contains `phone`.

2. Implement function `findPhoneByName` with signature

`findPhoneByName(name: string): string`. Returning phone from hash/object.

Use `hash[key]` to find needed phone.
