Use default arguments instead of short circuiting or conditionals

Default arguments are often cleaner than short circuiting. Be aware that if you use them, your function will only provide default values for undefined arguments. Other “falsy” values such as '', "", false, null, 0, and NaN, will not be replaced by a default value.

Bad:

function createMicrobrewery(name) {
  const breweryName = name || "Hipster Brew Co.";
  // ...
}

Good:

function createMicrobrewery(name = "Hipster Brew Co.") {
  // ...
}
