Redeclaration of Love

Assign, re-assign

Remember the let keyword used to declare new variables.

Note that we can't have multiple variables with the same identifier otherwise JS wouldn't know which one is which.

Redeclaring a variable will crash !

But it is still possible to use the = (assignation operator) to change its value !

Instructions

The variable love has been declared and will be used during the tests.

You must try to re-assign the love variable to the string value I still love you !! but without re-declaring it !

Note that sometimes you may find variable declared with const. This means that the assignation is constant and can never be re-assigned !

It is used to protect your code against errors, but you can always use let in its place.

Also you may find online old code using var. We are trying to get rid of var's since 2015. It's ancient syntax and it was pretty problematic. Never use it! If you see code using it, try to find a more recent example. This one is outdated.
