same snippets as https://github.com/gaboesquivel/atom-standardjs-snippets but for Visual Studio Code

Standard JavaScript Snippets for Visual studio code

A collection of ES6 snippets for faster JavaScript development in Atom Editor.

This collection is complementary to atom/language-javascript. It's based on extrabacon/atom-turbo-javascript and it enforces standardjs code style.

Yes!, no semicolons:

• Are Semicolons Necessary in JavaScript?
• An Open Letter to JavaScript Leaders Regarding Semicolons
• JavaScript Semicolon Insertion - Everything You Need to Know

Making the snippets to priority

I certainly prefer snippets to have the top priority in the autocompletion. This is not a default settingm but can be enabled by:

"editor.snippetSuggestions": "top",

in your settings.json. Otherwise vscode prefers keywords on the top.

Snippets

Snippets are optimized to be short and easy to remember. Some snippets are "chainable" and render differently when preceded by a "."

For example, .fe renders a chain-friendly version of the "forEach" snippet, while fe renders a full code block.
