Interface MutableChildSet

The sideEffect is executed for every entry in the Collection.

Unlike Array#forEach, if any call of sideEffect returns false, the iteration will stop. Returns the number of entries iterated (including the last iteration which returned false).

Returns a new Set with values passed through a mapper function.

OrderedSet([ 1, 2 ]).map(x => 10 * x)
// OrderedSet [10, 20]

An iterator of this Collection's values.

Note: this will return an ES6 iterator which does not support Immutable.js sequence algorithms. Use valueSeq instead, if this is what you want.
