// Place your advent-of-code-2023 workspace snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and
|
||||
// description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope
|
||||
// is left empty or omitted, the snippet gets applied to all languages. The prefix is what is
|
||||
// used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
|
||||
// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders.
|
||||
// Placeholders with the same ids are connected.
|
||||
// Example:
|
||||
// "Print to console": {
|
||||
// "scope": "javascript,typescript",
|
||||
// "prefix": "log",
|
||||
// "body": [
