   • variables
     • var = camelCase

       • value can be changed
     • printed out with console.log(name of the var)
     • mixed with strings in console.log
       • console.log("what time is it?", myTime) and var is printed after question
       • string interpolation
         • We can use the + operator from earlier to interpolate (insert) a variable into a string, like this: var myPet = 'armadillo'; console.log('I own a pet ' + myPet + '.'); // Output: 'I own a pet armadillo.'
   • data type
     • string
     • number
     • boolean
   • console
     • console.log()
   • math operators *+/-
     • modulus
       • 13%5=3 remainder
     • random generation
       • Math.random() * the max number you want, limit, could be decimal without Math.floor() capsulating it, rounds it to closest number
   • comments
     • single line //
     • multiple lines /* */
   • Control Flow
     • if/else Statements
       • var needCoffee = true; if (needCoffee) { console.log('Finding coffee'); } else { console.log('Keep on keeping on!'); }

     • Comparison Operators
       • Less than: < Greater than: > Less than or equal to: <= Greater than or equal to: >=
       • they will always return a boolean (true or false).
       • to check if two things equal each other, we can use ===
       • To check if two things do not equal each other, we can write !==
     • else if Statements
       • We can add more conditions to our if/else statement with: else if
         • The whole thing ends with the singular else
           • if (stopLight === 'red') { console.log('Stop'); } else if (stopLight === 'yellow') { console.log('Slow down'); } else if (stopLight === 'green') { console.log('Go!'); } else { console.log('Caution, unknown!'); }
