The only thing that would happen is that you need to assign it a value from the beginning and its value can't be reasigned, however, if you have an array or an object assigned to a const, you can still change their properties

After first initialization , if you try to modify the value in it error will be thrown which can be viewed in console.

In case of Array / Objects you can modify its properties or add / remove items in it. But it will throw error if you are assigning new array or objects to it.
