unicorn/no-unnecessary-array-splice-count

splice(start) and toSpliced(start) already remove everything from start to the end of the array. Passing the array's .length, Infinity or Number.POSITIVE_INFINITY as the second argument does the same thing with more code.

--fix removes the second argument.

Configure

Off by default. To turn it on:

[lint.rules]
"unicorn/no-unnecessary-array-splice-count" = "error" # or "warn"

Examples

Reported:

queue.splice(3, queue.length);
queue.splice(3, Infinity);

const firstThree = queue.toSpliced(3, Number.POSITIVE_INFINITY);

Not reported:

queue.splice(3);

const firstThree = queue.toSpliced(3);

// a real count, the length of another array, or items to insert
queue.splice(3, 2);
queue.splice(3, removed.length);
queue.splice(3, queue.length, next);
