Reading

From the Duckett HTML book:

• Chapter 3: “Lists” (pp.62-73)
• Chapter 13: “Boxes” (pp.300-329)

From the Duckett JS book:

• Review from Reading 02 - Chapter 2: “Basic JavaScript Instructions” (pp.70-73)
• Chapter 4: “Decisions and Loops” from switch statements on (pp.162-182)

ordered vs unordered lists

• <ul>
<li>something listed</li>
</ul>
  

• <ol>
<li>first</li>
</ol>

Boxing

` margin: 0;<br> padding: 0;<br> border: 0;<br> font-size: 100%;<br> font: inherit;<br> vertical-align: baseline;`
}

if .. else statements

• checks a condition

• if it resolves true…

• execute code

if (rain = no) { plant(); } else { ` wait();`

}

switch statement

• example let review = prompt(‘On a scale of 1-7, please submit a number which you rate our site as: 1 being terrible, 7 being the best you ever saw’);

console.log(typeof review);

let reviewNumber = parseInt(review);

<!-- switch (reviewNumber) { case 1: alert(userName + ', please join our team to help us!'); break; case 2: alert(userName + ', please join our team to help us!'); break; case 3: alert(userName + ', please join our team to help us!'); break; case 4: alert(userName + ', please join our team to help us!'); break; case 5: alert(userName + ', please join our team to help us!'); break; case 6: alert(userName + ', please spread the word!'); break; case 7: alert('woot woot!!! good job '+ userName); break; default: alert('Enjoy your time ' + userName) -->

Data Types

• string
• number
• boolean
• null
• undefined

- falsy and truthy values

Loops

For – While – Do While

For
Runs code specific number of times

• most common

While
Not not sure how many times it will need to be run

• if condition is true, code runs

Do While
Similar to while loop

• will always run at least once even if evaluates to false

for (var i=0; i < 10; i++)

{document.write(i);}

Decisions & Loops

• conditions allow code to make decions about what happens
• comparison operators dictate (===,!==,==,!=,<,>,<=>)
• if .. else .. allow you to break away in a direction depending on true v false
• data types can be “coerced”
