Features

• Deep immutability, Enumerable is immutable. But, in addition, also all its content is immutable, don't worry to modify an object, don't worry about side effects.

  const foo = { foo: 'bar' };
  const bar = Enumerable
                    .from(foo)
                    .first();
  console.log(foo === bar); // false
  // while
  // const bar = [foo][0];
  // foo === bar is true
  

• Advanced object comparison, by default Enumerable uses a deep comparison algorithm to make it works. Objects are not compared by reference.

  const foo = { foo: 'bar' };
  const bar = { foo: 'bar' };
  const result = Enumerable
                      .from(foo)
                      .includes(bar);
  console.log(result); // true
  // while
  // [foo].includes(bar) is false
  

• Configurable, by default Enumerable is deep immutable and uses an advanced object comparison algorithm, but you can enable and disable these features based on your needs.
• Linq syntax, high compatible C# Linq syntax makes query easier and immediate to use.
• Lightweight
