+// Complete the following assignment on JavaScript 1 and push your file to GitHub for reviewing by the instructor.
+
+// For all the following exercises create one .js file. Separate the questions using comments.
+
+// Write a console.log statement saying "Hello World!" for each language that you know.
+// For example:
+
+// Halo, dunia! // Indonesian
+
+// Ciao, mondo! // Italian
+
+// Hola, mundo! // Spanish
+
+console.log('Merhaba Dunya');
+console.log('Hello World');
+console.log('Hola, mundo!');
+
+// Consider the following code:
+// console.log('I'm awesome');
+// Copy the code in your .js file and run it. You will see that you will get a SyntaxError. Find a solution for this error. Hint: read the error message carefully, it also gives an indication of where the problem is.
+
+console.log("I'm awesome");
+
+// Declare a variable age and initialize it with an integer, using these exact steps:
+let age;
+
+// First, declare your variable age (do not initialize it yet).
+// Add a console.log statement that explains in words what you think the value of age is
+
+console.log('age is undefined');
+
+// Add a console.log statement that logs the value of age.
+console.log(age);
+
+// Now initialize your variable age with an integer.
+age = 33;
+// Next, add a console.log statement that explains what you think the value of age is.
+console.log('it is 33');
+// Add a console.log statement that logs the value of age.
+console.log(age);
+// Example steps for question 3:
+//   // TODO -> here you declare your variable
+//   console.log('the value of age will be: whateverYouThinkItWillLog');
+//   // TODO -> log the actual value of age
+//   // TODO -> here you initialize your variable
+//   console.log('the value of age will be: whateverYouThinkItWillLog');
+//   // TODO -> log value of age again
+
+// Declare a variable name and assign a string to it.
+let aString = 'world';
+// Write a console.log statement in which you explain in words what you think the value of the string is.
+console.log('it is world');
+// Now console.log the variable name.
+console.log(aString);
+// Now assign a new string to the variable name.
+aString = 'Jupiter';
+// Just like what you did before write a console.log statement that explains in words what you think will be logged to the console.
+console.log('it is Jupiter');
+// Now console.log name again.
+console.log(aString);
+// Example steps for question 4:
+
+//   // TODO -> here you declare AND assign your string
+//   console.log('the value of my string will be: whateverYouThinkItWillLog');
+//   // TODO -> log the actual value of the string to the console
+//   // TODO -> assign a new value to your variable name
+//   console.log('the value of my string will be: whateverYouThinkItWillLog');
+//   // TODO -> log the actual value of the string to the console
+
+// How do you round the number 7.25, to the nearest integer (i.e., whole number)?
+Math.round(7.25);
+console.log(Math.round(7.25));
+// Declare a variable number and assign the number 7.25 to it.
+aNumber = 7.25;
+// console.log number.
+console.log(aNumber);
+// Declare another variable roundedNumber that has the value of number but rounded to the nearest integer.
+roundedNumber = Math.round(aNumber);
+// console.log number.
+console.log(roundedNumber);
+// So now we have number and roundedNumber find a way to compare the two values and store the highest of the two in a new variable.
+
+let highestNumber;
+if (aNumber > roundedNumber) {
+  highestNumber = aNumber;
+} else {
+  highestNumber = roundedNumber;
+}
+
+// console.log the highest value.
+console.log(highestNumber);
+// Arrays
+
+// Declare an empty array. Make sure that the name you choose indicates 'plurality', because an array is capable of containing more than one element.
+const arr = [];
+// Write a console.log statement that explains in words what you think the value of the array is.
+console.log('arr does not have any value');
+// console.log your array.
+console.log(arr);
+// Create an array that has your favorite animals inside (see if you can find a good name that exactly describes what this variable will hold).
+const myFavouriteAnimals = ['cat', 'lion', 'bird', 'sheep', 'cow', 'donkey'];
+// Log your array.
+console.log(myFavouriteAnimals);
+
+// Add a statement that adds Syeda’s favorite animal ('kitten') to the existing array.
+myFavouriteAnimals.push('kitten');
+
+// Log your new array
+console.log(myFavouriteAnimals);
+// More strings: Let's consider the following string: let myString = "this is a test".
+let myString = 'this is a test';
+// Add the string to your file and console.log it.
+console.log(myString);
+// Find a way to get the length of myString.
+myString.length;
+// console.log the length of myString.
+console.log(myString.length);
+
+// If x equals 7, and the only other statement is x = x % 3, what would be the new value of x?
+let x = 7;
+x = x % 3;
+console.log(x);
+// Add at least 3 console.log statements in which you show that you understand what % does.
+console.log(
+  '% is used to show remainder of the first number when divided to the second'
+);
+console.log('8%5 is equal to 3 ==> ' + (8 % 5));
+console.log('9%5 is equal to 4 ==> ' + (9 % 5));
+console.log('10%5 is equal to 0 ==> ' + (10 % 5));
+// Write a program to answer the following questions:
+
+// Can you store multiple types in an array? Numbers and strings? Make an example that illustrates your answer.
+console.log(
+  'Yes I cam store multiple types in an array but it is not a good practice'
+);
+const arrayWithMultipleTypes = [5, 'this array has both a string and a number'];
+console.log(arrayWithMultipleTypes);
+// Can you compare infinities? Does 6/0 === 10/0? How can you test this?
+console.log(
+  'I was thinking as if Infinitys are not comparable but according to the following test, they are comparable and Infinity = Infinity'
+);
+
+// Add console.log statements to the above program in which you show that you understand the concepts (just like you've done in the above assignments).
+
+if (6 / 0 === 10 / 0) {
+  console.log('infinities are comparable');
+} else {
+  ('infinities are not comparable');
+}
+let a = 6 / 0;
+let b = 10 / 0;
+console.log(a);
+console.log(b);
+console.log(a === b); // this is returning true
+
+// I’ve declared a multidimensional array (an array inside an array) -- see below. How can I access the third item’s second element? i.e. [2, 1] is the third element, and I want to access 1. Add a console.log statement accessing this item.
+// const grid = [[0, 1], [1, 1], [2, 1], [3, 1]];
+const grid = [[0, 1], [1, 1], [2, 1], [3, 1]];
+console.log(grid[2][1]);
+
+// If I have a variable counter, and I want to increment it by 2, what are three ways I can do this? Add three console.log statements with the three different ways.
+// let counter = 0;
+// console.log(‘first method’);
+let counter = 0;
+counter += 2;
+console.log('first method: ' + counter);
+counter = counter + 2;
+console.log('second method: ' + counter);
+counter++;
+counter++;
+console.log('third method: ' + counter);
+
+// 12. Here’s a profile about a cat for adoption. Create variables to hold information about this cat as shown on the profile. For example:
+
+// const name = ‘Prince’;
+// const bestFriend = ‘Thomas’;
+
+const name = 'Prince';
+const bestFriend = 'Thomas';
+const breed = 'Domestic Shorthiair';
+const sex = 'male';
+const color = 'Orange or Red Tabby';
+const age = '1 year old, Young';
+const hair = 'short';
+const DOB = 'July 28, 2018';
+const info = [
+  'Neutered',
+  'Good with Kids',
+  'Shots up to date',
+  'good with cats'
+];
+
+//13. Create two variables -- one to hold the names of the kittens and one to hold the names of the adult cats. Make sure to choose an appropriate data type to hold this information!
+
+const kittenNames = ['Kyle', 'Luna', 'Obi', 'Raspberries', 'Charlie'];
+const adultNames = ['Mezzo', 'Sabrina', 'Josie'];
