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(test1);
const test1 = '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.
