## 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 !
