Create variables and manipulate the values.

Check what happens when you try concatenating strings using variables of different data types.

Interpolate multiple variables into a string.

See what happens when you use console.log$()$ on variables declared by different keywords $($const$,$ let, var$)$ before they$$re defined. For example:

console.log$($test$1)$;

const test$1=$ 'figuring out quirks';

Find the data type of a variable$$s value using the typeof keyword on a variable.

Use typeof to find the data type of the resulting value when you concatenate variables containing two different data types.
