Javascript style ================ Basics: - Indent with 2 spaces. - Keep a maximum line length of 120 characters. - Prefer "double quotes" for strings/ - Never omit optional semicolons. - Do not put opening braces or brackets on a new line. - Call functions without spaces: foo(bar) - Use 'let' instead of 'var' whenever possible. - Declare "use strict;". - Use rocket (=>) syntax for anonymous functions. If an anonymous function is too long, make it a named function. - Document functions with JSDoc comments (http://usejsdoc.org). Names: - Use PascalCase for classes/types, camelCase for variables, functions and properties, UPPER_SNAKE_CASE for constants, kebab-case for event names. - Only capitalize the first letter of an acronym in identifiers. APIs: - Prefer 'Promise' to one-shot continuations whenever possible.
