PreferSpreadOverApply [rule] v0.1.0

When passing a list of values as positional arguments, spread the array (fn(...args)) instead of calling fn.apply(null, args). When collecting variadic arguments, use rest parameters (function fn(...args)) instead of inspecting the legacy arguments object. Both spread and rest are dedicated syntax for the job, and both compose cleanly with arrow functions.

Checks

• Variadic forwarding is wrapper(...args), not wrapper.apply(this, args).
• Variadic capture is function fn(...args) { … }, not function fn() { var args = arguments; … }.
• Array copy is [...source] or Array.from(source), not source.slice() followed by mutation patterns.
• Object copy / merge is { ...source, override }, not Object.assign({}, source, { override }) (both work; spread is the style choice).

Label

Prefer the spread operator over .apply() and arguments-based variadic plumbing
