⚠ Redundant constant declaration.
> 1 │ const FOO = “FOO”;
│ ^^^^^^^^^^^
2 │ console.log(FOO);

ℹ Used here.
1 │ const FOO = “FOO”;
> 2 │ console.log(FOO);

ℹ You should avoid declaring constants with a string that’s the same
value as the variable name. It introduces a level of unnecessary
indirection when it’s only two additional characters to inline.
ℹ Unsafe fix: Use the constant value directly
1 │ - const·FOO·=·“FOO”;
2 │ - console.log(FOO);
