/**

* The spec generates a pattern like this '^\d{3}-\d{2}-\d{4}$'

* However, to use it in HTML or inside new RegExp() we need to

* escape the pattern to become: '^\\d{3}-\\d{2}-\\d{4}$' in order

* to make it a valid regexp string.

* Also, escape single quote characters, because the output uses single quotes for strings

* @param pattern

export const getPattern = (pattern?: string): string | undefined => {

// eslint-disable-next-line prettier/prettier

return pattern?.replace(/\\/g, '\\\\').replace(/'/g, "\\'");

};
