@putout/plugin-add-missing-new

The Set constructor lets you create Set objects that store unique values of any type, whether primitive values or object references.

(c) MDN

🐊Putout plugin adds ability to add missing operator new, since built-in objects:

• Set;
• WeakSet;
• Map;
• WeakMap;
• Int8Array;
• Uint8Array;
• Uint8ClampedArray;
• Int16Array;
• Uint16Array;
• Int32Array;
• Uint32Array;
• Float32Array;
• Float64Array;
• BigInt64Array;
• BigUint64Array;

Produces TypeError when called without new like this:

Uncaught TypeError: Constructor Set requires 'new'
