Basic Rules

• no semicolons
• 2 spaces
• single-quotes
• strict mode
• always use braces
• prefer arrow functions
• use const and let, prefer const
• use === and !==
• no magic numbers (excluding -1 through 2)
• use object shorthand
• use destructuring

Functions

Named functions

• no space after function name
• 1 space after function parens

function foo(bar, baz) {
  // do work
}

Anonymous (Arrow) Functions

• 1 space before and after arrow
• no superfluous return

// good
const foo = (bar, baz) => foo + bar
const foo = (bar, baz) => ({ bar, baz })

// bad
const foo = (bar, baz) => {
  return foo + bar
}
const foo = (bar, baz) => {
  return { bar, baz }
}

Function Chains

Function chains longer than 3 should be broken onto new lines

// good
_(foos)
  .map(transformFoos)
  .filter(applyFilter)
  .value()
_(foos)
  .map(transformFoos)
  .filter(applyFilter)
  .map(transformFoosAgain)
  .value()

// bad
_(foos)
  .map(transformFoos)
  .filter(applyFilter)
  .map(transformFoosAgain)
  .value()
