OneBindingPerDeclaration [rule] v0.1.0

Write const a = 1; const b = 2; rather than const a = 1, b = 2;. One declaration per binding makes diffs cleaner, lets you initialise each from a different expression without contortions, and avoids the trap of accidentally giving every name in a comma-separated list the same const-vs-let modifier.

Checks

• No const a = 1, b = 2 patterns — each binding is its own statement.
• ESLint one-var rule set to ["error", "never"] (or equivalent).
• Destructuring counts as one binding for this rule: const { a, b } = obj is fine, since the source is a single expression.
