History.go: History.go requires a positive or negative integ

Error message

History.go: History.go requires a positive or negative integer passed.

What it means

History.go(index) only accepts a non-zero integer: positive moves forward, negative moves backward. Passing 0 (or a value that is neither >0 nor <0) falls through both branches and throws, because moving by zero states is meaningless.

Solutions

1. Guard: only call History.go when index is a non-zero integer.
2. No-op explicitly when index === 0 rather than calling History.go.
3. Coerce and validate: if (!index || !Number.isInteger(index)) return;

Example fix

// before
History.go(delta); // delta may be 0

// after
if (Number.isInteger(delta) && delta !== 0) History.go(delta);

function historyGo(index) {
  if (!Number.isInteger(index) || index === 0) return;
  History.go(index);
}

function isNonZeroInteger(v) {
  return Number.isInteger(v) && v !== 0;
}

When it happens

Trigger: Calling History.go(0); calling History.go(someVar) where someVar is 0, undefined coerced to 0, or NaN.

Common situations: Passing a computed delta that can be zero; user input (e.g. 'go N steps') with N=0; off-by-one in pagination logic.
