Lesson #7

Control Flow

• This is how the script is read, usually top to bottom line by line

Functions

• Functions in JavaScript are as follows: function FUNCTION_NAME(PARAMETRE) {CODE INSIDE THESE}
• The function then won’t be ran until the name of it is used somewhere in the code
• A function can be called upon at any point of a script and the function doesn’t need to be in the same script

Operators

• Operators are mathmatical symbols, +, -, * and /

Comparators

• Is == which says is it equal to instead of setting
• != means not equal to

• , <, <=, >= etc etc these are also comparators

• === Means strictly equal to, you can not change it always equals x
• !== Strictly not equal to

Comparisons

• This is when you compare 2 different values

Expression

• This is a code that is evaluated and resolves to a value

Conditions

• These are conditions that have to be met for the if statement to run

Parameters

• This is inside of the brackets of a function ready to be set
• Seperate each parameter with a ,

Arguments

• This is when you define the parameter after the function
