The result is balanced. {{jsxref(\"Temporal/Duration/negated\", \"Temporal.Duration.prototype.negated()\")}} : Returns a new Temporal.Duration object with the negated value of this duration (all fields keep the same magnitude, but sign becomes reversed). {{jsxref(\"Temporal/Duration/round\", \"Temporal.Duration.prototype.round()\")}} : Returns a new Temporal.Duration object with the duration rounded to the given smallest unit and/or balanced to the given largest unit. {{jsxref(\"Temporal/Duration/subtract\", \"Temporal.Duration.prototype.subtract()\")}} : Returns a new Temporal.Duration object with the difference between this duration and a given duration (in a form convertible by {{jsxref(\"Temporal/Duration/from\", \"Temporal.Duration.from()\")}}). Equivalent to adding the negated value of the other duration. {{jsxref(\"Temporal/Duration/toJSON\", \"Temporal.Duration.prototype.toJSON()\")}} : Returns a string representing this duration in the same ISO 8601 format as calling {{jsxref(\"Temporal/Duration/toString\", \"toString()\")}}. Intended to be implicitly called by {{jsxref(\"JSON.stringify()\")}}. {{jsxref(\"Temporal/Duration/toLocaleString\", \"Temporal.Duration.prototype.toLocaleString()\")}} : Returns a string with a language-sensitive representation of this duration. In implementations with Intl.DurationFormat API support, this method delegates to Intl.DurationFormat. {{jsxref(\"Temporal/Duration/toString\", \"Temporal.Duration.prototype.toString()\")}} : Returns a string representing this duration in the ISO 8601 format. {{jsxref(\"Temporal/Duration/total\", \"Temporal.Duration.prototype.total()\")}} : Returns a number representing the total duration in the given unit. …\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
