JSHint prevent redeclared global variable

I am using JSHint and I have a global variable (test) declared using the predef options. However in my code I can just override the global variable using
var test = 4;
Is there anyway to prevent this? I want to use my global variable without being able to override it in any way.

Useconstinstead ofvar.If your variable is a primitive, like number or string, it can't be overriden.

@HynekS It can't be overridden directly, but could still be overridden in scope, which I think the op might be trying to prevent. eg.const x = 1; { let x = 2; console.log(x); }will still return 2.

@HynekS, Yea Keith was right, I am aware how const works, but using const or var, my global variable test still gets overridden in the scope and I lose all previous data :(
