- strings ("This is a string", "42", "is also a string")
- Booleans
- true or false statements, such as (7<10) or (10<7)
- if/else
- used to send code down different paths
if( condition) { code code code; } else if { code code code; } else { code code code; }
- var
- variable that can be determined or given
var MeaningofLife = 42
- function
- follow the same instructions by calling on a single variable.
//This is what a function looks like var divideByThree = function (number) { var val = number / 3; console.log(val); }; //On line 11, we call the function by name //Here, it is called 'dividebythree' //We tell the computer what the number input is (ie. 6) //The computer then uses the code inside the function divideByThree(12);
- loop
- loops a specified response until condition is met
for(var i = 100 ; i >= 0 ; i -=5 ) { console.log(i); }
