Variable

A variable is a named **container for** a particular set of bits or type of **data** (like integer, float, string, etc...).[1]

THe general pattern is keyword (let, const, etc.), name, assigned value (= ...) the ==... initializes the variable. You can declare variables without initializing them.

See var in MDN

See let in MDN The let declaration declares re-assignable, block-scoped local variables, optionally initializing each to a value.

"let" is the command to create a variable. It must be followed by a name for that data store. This named variable must be followed by, =, which means, assign the following to this named data store. The = is followed by the data itself or a pointer or calculation that yields the data that will be placed in the named data store.

Notes on **variable naming conventions**: Only & and _ are allowed, though not recommended. No other special characters. camelCase is recommended. Numbers can be used, just not as first characters of names.

let varableName = 'Particular Name';
