const Does Not Allow Hoisting
As discussed in the previous chapter, let does not allow hoisting i.e. we cannot use a variable before the declaration. Just like let we can not use hoisting with the const.it is only supported with var.
MYPLANET = 'earth'; console.log(MYPLANET); const MYPLANET;
Tarea
Rearrange the following code to display the value of SALARY on the console.
Summary:
- We can neither change the values of the
constvariables through reassignment nor we can redeclare them. - Value should be assigned to
constvariables at the time of declaration.
