Toggle

Noun · Development

Definitions

  1. A switch that alternates between two states (on/off, enabled/disabled). In UI it's a visual switch control; in backend systems, a feature toggle (or feature flag) is a runtime switch that enables or disables functionality without redeploying code.

    In plain English: An on/off switch — either a visual control in the interface or a behind-the-scenes switch that turns features on or off.

    Example: "We hid the new onboarding flow behind a toggle so we can enable it for 10% of users and kill it instantly if metrics drop."
