SEI Week 1 Assessment

Bash (Terminal)

For EACH and EVERY question in this section, assume you are in the ~/buffy directory:

1. Make two directories inside ~/buffy: scoobies and vamps:
   
   
   

2. Create files in scoobies named buffy.txt and angel.txt:
   
   
   

3. Copy angel.txt into the vamps directory:
   
   
   

4. Delete the vamps directory and everything inside it:
   
   

JS Variables

1. Assign the string "Ahab" to a variable named captain:
   
   

2. Using the captain variable instead of the text "Ahab", use string concatenation to form the string "Oh Ahab, my Ahab!", assigning it to a variable named phrase:
   
   

JS Conditionals

var souls = 3;
var lifeRafts = 2;

1. Assuming the above variables, write an if statement that console.logs "SOS!" if there are more souls than lifeRafts (no need to write a function, just the if statement please):
   
   

Data Structures - JS Arrays

1. Create an array named weekend with just a string 'Saturday' in it:
   
   

2. Add the string 'Sunday' to the end of the weekend array:
   
   

3. Now add the string 'Friday' to the front of the weekend array:
   
   

4. Using square bracket notation, access 'Saturday' in the weekend array and assign to a variable named day (Note: the array has three days in it as this point):
   
   

5. Remove 'Friday' from the array:
   
   

6. Loop through the weekend array and for each element in it, print "Woohoo! It's finally <day name>"

Data Structures - JS Objects

Don't forget to use a var or let when defining new variables...

1. Write an object literal named brain having a property with a key of energyLevel and a numeric value of 10:
   
   

2. Assign the value of the property energyLevel to a variable named energy:
   
   

3. Add a dream property to the brain object that holds the string 'electric sheep':
   
   

JS Functions

1. Write a function named computeArea that has two parameters, length & width, and returns the area of a rectangle (the product of length and width):
   
   
   
   

2. Invoke the computeArea function with 3 and 4 as arguments and save the returned result to a variable named area:
   
   

3. Write a function findMax that takes in 1 paramater, an array of numbers, and returns the highest number in that array.
