Before building this library you need to install the npm package manager.
Check out this project and run this command from the root of the project:
$ make
This will generate cp-data.js
and cp-data.min.js
in the out/dist
directory
of the project.
var Set = require('cp-data').Set;
var s1 = new Set();
s1.has(1);
// => false
s1.add(1);
// => true
s1.size();
// => 1
s1.has(1);
// => true
// Addind a key that is already in the set does not change the set. The
// function returns `false` to indicate nothing changed.
s1.add(1);
// => false
s1.size();
// => 1
s1.add(2);
s1.size();
// => 2
// We can construct a set from an array
var s2 = new Set([2, 3, 4]);
s2.keys();
// => [2, 3, 4]
// Intersection:
Set.intersect([s1, s2]).keys();
// => [2]
// Union:
Set.union([s1, s2]).keys();
// => [1, 2, 3, 4]
// We can also do set intersection / union with arrays:
Set.intersect([[1, 2, 3], [2, 3, 4]]).keys();
// => [2, 3]
// We can do set intersection / union with more that 2 sets:
Set.union([s1, s2, ['a', 'b', 'c']]).keys();
// => [1, 2, 3, 4, 'a', 'b', 'c']
// Lastly, sets preserve the type of the key supplied. Compare the following 2
// results:
new Set([1]).keys();
// => [1]
new Set(['1']).keys();
// => ['1']
