# static template

## `TypeError.template`

A template of the error message of [`string`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String) type with the replaceable [`{problem}`](/draft-5/commonerror/properties/static-template.md#problem), [`{fix}`](/draft-5/commonerror/properties/static-template.md#fix) and optional [`{id}`](/draft-5/commonerror/properties/static-template.md#id), [`{max}`](/draft-5/commonerror/properties/static-template.md#max), [`{min}`](/draft-5/commonerror/properties/static-template.md#min), [`{type}`](/draft-5/commonerror/properties/static-template.md#type) tags.

By default, it's set to `Problem{id}: {problem} => Fix: {fix} must be of the {type}`.
