# Variable

The `Variable` is an extension of the [`Tag`](/tag/tag.md) string object and represents an [immutable](https://developer.mozilla.org/en-US/docs/Glossary/Immutable) variable in the form of name between curly brackets e.g. **`{fix}`** with the ability to set its value.

### Instance accessors

| Variable.prototype.                                                                                               | Description                                                                                                                                                                                                                                                                    |

| [value](https://text.angular-package.dev/tag-variable/pages/twcBY1hCusIQFq090LaA#variables.prototype.value)       | The [`get`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get) accessor returns the value from a private [`#value`](/tag-variable/variable/instance-properties.md#value) property of a specified [`Variable`](/tag-variable/variable.md) object. |
| [variable](https://text.angular-package.dev/tag-variable/pages/twcBY1hCusIQFq090LaA#variables.prototype.variable) | The [`get`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get) accessor returns the variable in form `{variable name}`, a primitive value of the specified [`Variable`](/tag-variable/variable.md) object.                                       |

### Static methods

| Variable.                                                                                                    | Description                                                                                                         |

| [define()](https://text.angular-package.dev/tag-variable/pages/EIokaaHnUz9B6mnfDs2j#variable.define)         | The static method defines the [`Variable`](/tag-variable/variable.md) of a specified name with an optional value.   |
| [isVariable()](https://text.angular-package.dev/tag-variable/pages/EIokaaHnUz9B6mnfDs2j#variable.isvariable) | The static method checks whether the value of any type is an instance of a [`Variable`](/tag-variable/variable.md). |

### Instance methods
