are you using prettier formatter to format your code on save? I recommend it, as it will fix issues like this where the space should be after the comma not before

you can also add all arguments into the .concat() method call, e.g.
return firstWord.concat(" ", secondWord, " ", thirdWord);

you could use a variable name for the number 1.2 so it's more meaningful, e.g.
const totalPlusTax = 1.2;
let priceOfProduct = number * totalPlusTax;

It's better practice to declare a new variable, rather than reassign the value of a parameter, e.g.
const priceWithTax = calculateSalesTax(pound);

👍 very nice use of .toFixed() and string interpolation

Math.random() returns a number greater than or equal to 0 and less than 1, so this returns a number greater than or equal to 0 and less than 10
