Pair classes for TypeScript and JavaScript

Install

npm install ts-pair --save

Example

let pair = new Pair( 1, "Hello" );
console.log( pair.first, ', ', pair.second ); // 1, Hello
console.log( 'Pair is ' + pair ); // Pair is [ 1, Hello ]

pair.first = 2;
pair.second = "hi";

console.log( 'JSON', pair.toJSON() ); // Pair is { "first": 2, "second": "hi" }

let [ first, second ] = pair.toArray();
console.log( first, second ); // 2, hi

// chainable
console.log( pair.setFirst( 10 ).setSecond( "bye" ).toString() ); // [ 10, bye ]

let otherPair = new Pair( 20, "bye" );
console.log( otherPair.equals( pair ) ? 'equal': 'different' ); // different

let aImmutable = new ImmutablePair( 20, "bye" );
console.log( aImmutable.equals( otherPair ) ? 'equal': 'different' ); // equal

aImmutable.first = "baz"; // Error
