Learning Activity $1\mathrm{.}1\mathrm{.}3$: JS Review and Practice

Learning Objectives

Refresh your JavaScript skills

Learn some new JavaScript concepts and tricks

Directions

$1.$Use basic JavaScript programming concepts. Download the example LA$1\mathrm{.}1\mathrm{.}3\_$JS$\_$basic.rar. Extract and open it to your development environment. Review the examples.

$2.$Write a program to display different types of triangles using nested loop.

$3.$Create a simple web application that explains for$-$of$,$ for$-$in$,$ for, foreach, map. Use example codes to demonstrate your answer.

$4.$Write a JavaScript program that determines if an input number is even or odd. Your code should run from terminal as well as browser with minor modification.

$5.$Write a JavaScript program that prints the factorial of any given integer. The factorial of number n equals $1\backslash$times $2\backslash$times $3\backslash$times $...\backslash$times $($n$-2)\backslash$times $($n$-1)\backslash$times n$.$ Code should run on terminal and browser with minor modification.

$6.$Write a JavaScript program that displays even numbers and odd numbers in different rows. Your program should accept initial and maximum value from the user and print out all the results on the browser. For example, if the initial is $4$ and maximum is $17$ then your program should display all even numbers between $417$ in one row and all odd numbers in another row. Write code for No$\mathrm{.}5$ in LA$1\mathrm{.}1\mathrm{.}3$ and for number $5$ for integer. Implement the functionality by $4$ different ways $($while loop, for loop, function, recursion$).$ Save your code in one js file and run this file in node. Submit this js file.
