Incremental integer counter. Counts from 0 to very big intergers. Javascript´s number type allows you to count in integer steps from 0 to 9007199254740991. As of ES5, Strings can contain approximately 65000 characters and ES6 is supposed to handle the MAX_SAFE_INTEGER (though I don´t believe any environments supports this). This counter represents integer values as strings and can therefore count in integer steps from 0 to the maximum string length (that´s some 65000 digits). In the lower range, upto 9007199254740991, the strings can be converted to safe Javascript integers Number(value) or +value. This counter is great for any applications that need a really big count represented as a string, (an ID string).

Example

import BigCounter from 'big-counter-x';

const counter = new BigCounter();

console.log(counter.get()); // '0'
console.log(counter.next()); // counter object
console.log(counter.get()); // '1'

// Methods are chainable.
console.log(counter.next().next()); // counter object
console.log(counter.get()); // '3'

console.log(counter.reset()); // counter object
console.log(counter.get()); // '0'
console.log(counter.toString()); // '0'
console.log(counter.valueOf()); // '0'
console.log(counter.toJSON()); // '0'

// Values upto `9007199254740991` convert to numbers.
console.log(Number(counter)); // 0
console.log(+counter); // 0
