I finished the Variables chapter in Javascript and some notes as below:
-
Variables hold reusable data in a program and associate it with a name.
-
Variables are stored in memory.
-
The
varkeyword is used in pre-ES6 versions of JS. -
letis the preferred way to declare a variable when it can be reassigned, andconstis the preferred way to declare a variable with a constant value. -
Variables that have not been initialized store the primitive data type
undefined. -
Mathematical assignment operators make it easy to calculate a new value and assign it to the same variable.
-
The
+operator is used to concatenate strings including string values held in variables -
In ES6, template literals use backticks ``` and
${}to interpolate values into a string. -
The
typeofkeyword returns the data type (as a string) of a value.
I also wrote a brief Realm Byte on Embedded Objects
Until Tomorrow,
(I am going to trekk on SugarLoaf Mountains)
