// What is this script?
|
||
|
|
// We want to support code syntax highlighting in the embed modal, but we cannot afford to have the static build
|
||
|
|
// be large in size. To prevent HighlightJs from loading all 193+ language stylings and bloating the script, we instead take a large subset that
|
||
|
|
// covers most languages and then dynamically build and register each language since HLJS cannot just register with an array of langs.
|
||
|
|
// Since the embed is a single script - we need to statically import each library and register that associate language.
|
||
|
|
// we can then export this as a custom implementation of HLJS and call it a day and keep the bundle small.
