  Parameters

  • _delta: number

  Returns number

increment

• increment(_delta: number): number

  Increases the value of the counter by delta. If delta is not given, increases the value of the counter by 1.

toString

• toString(): string

  Returns the counter value as a decimal string. If x is a counter object, this method is called e.g. when you do ['value: ', x].join('') or when you use string interpolation: value: ${x}.

  Returns string

valueOf

• valueOf(): number

  A peculiar JavaScript language feature from its early days: if the object x has a valueOf() method that returns a number, you can use numerical operators on the object x directly, such as x + 1 or x < 4. This method is also called when coercing a value to a string by concatenating it with another string, as in x + ''. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/valueOf

  Returns number
