Task 1 'npm'

• Implement app that contains at least one dependency and one dev dependency

Task 2 'Coercion operations'

• Implement app that contains at least one dependency and one dev dependency

Task 3 'Objects'

• Create repo “add”
• Implement function that can “add” objects

example: a = {x: 1} b = {x: 2, y: 2} 
add(a, b) returns {x: 3, y: 2}
add(a, b, a) returns {x: 4, y: 2}

* Create additional function that can intersect object

Task 4 'Functions'

function randn_bm() {  
    let u = 0, v = 0;  
    while (u === 0) u = Math.random();  
    while (v === 0) v = Math.random();  
    return Math.sqrt(-2.0 * Math.log(u)) * Math.cos(2.0 * Math.PI * v) * 2 | 0;
}; 

• Using provided function generate 10 numbers. Create object with the keys related to the generated numbers and value as a quantity of corresponding number. Display numbers distribution as a table using template literal string.
• Example of object: {0: 5, 1: 3, 2: 2}

P.S.

Gaussian distribution on such a sample (10 numbers) is not obvious. It is better to take 50 numbers, so that the prevalence of 0 and numbers close to it is more noticeable.

Task 5 'Functions2'

• Implement function range(min,max) that can return sum of integer numbers in range [min,max]
• Consider edge cases: result is greater than Number.MAX_SAFE_INTEGER, argument is not a number, min > max, etc.
• *For performance reason add memoization mechanism

Task 6 'Memory management'

• Implement program to print all permutations of a given string

Example  
Input: ABC
Output: ABC, ACB, BAC, BCA, CAB, CBA

• *Print all permutations in sorted (lexicographic) order

Task 7 'Inheritance'

• Describe base class Entity that can store name
• Implement child classes Stuff, Box, User. Box can store some stuff[]. Every box belongs to user
• Add example of usage of these classes, e.g., create some instances, display data related to them

Task 8 'Arrays'

• Given array of numbers [x]. Find “approx” [y] array where yi = xi-1 + xi+1

Example: [1, 2, 3, 4] => [2, 4, 6, 3]

• *Write function that can perform this calculation for multidimensional arrays

Task 9 'DOM'

• Using js construct on page Tic-Tac-Toe layout
• Add possibility to interact with layout by mouse click (add “X” or “O”)
• Add module that can write down on page game result (1st win, 2nd win or draw)

Task 10 'Events'

• Add to html page table with header and some rows
• Add to header event listener to implement sorting functionality across the table data (alphabetical)
• Add to cells user interaction feature (click and edit text)

Task 11 'Asynchrony'

• Develop 4 functions that can perform operations +, -, *, / but return result with some random delay (> than 1sec)
• Create stack calculation module that can interact with mentioned before functions and handle Reverse Polish notation input
• Calculate “1 2 + 3 × 4 +”

Instructions

• For division use ":"
• Enter all numbers and signs of operations separated by a space. Example: '2 2 +'
• To display the result, the expression must contain calculation operations (+, -, *, :)

Task 12 'Network interaction'

• Develop page with two dropdowns "Title" and "Category"
• Values of selections should invoke render of data from https://api.publicapis.org/
• Handle possible error cases

Attention

In entrie no "title" only "API" (but, when specifying the URL, the "title" is used)

Task 13 'Modern js'

• Convert your code from previous HT by the Babel transpiler to ES5 version
• Check working status of app for different browsers

Сhecked on:

• IE 10, 11
• Edge
• Firefox
• Opera
• Chrome
• Яндекс

Task 14 'Module principle'

• Split your code from previous HM to some modules (at least 2)
• Implement dynamic import for module

Task 15 'User data manipulation'

• Develop page with stored state that can “restore” user name and predefined theme (dark or light)
• Apply this module to existing app (from previous task)
