== Why is this an issue?

Variables declared with ``++const++`` cannot be modified. Unfortunately, attempts to do so don't always raise an error; in a non-ES2015 environment, such an attempt might simply be ignored.


=== Noncompliant code example

[source,javascript]
----
const pi = "yes, please";
pi = 3.14;  // Noncompliant

ifdef::env-github,rspecator-view[]

== Implementation Specification
(visible only on this page)

=== Message

Correct this attempt to modify "xxx" or use "let" in its declaration.


=== Highlighting

* primary: var name in assignment expression
* secondary: const declaration
