avanzarVersion

Increments the version number following a custom versioning scheme where minor versions go from 0 to 8, then roll over to the next major version.

​
Function Signature

function avanzarVersion(version: string): string

​
Parameters

​
version
string
required
The current version string in the format “major.minor” (e.g., “1.5”, “2.8”)

​
Returns

​
version
string
The next version number according to the versioning rules:
  • If minor version is 8, increments major version and resets minor to 0
  • Otherwise, increments minor version by 1

​
Behavior

The function implements a specific versioning scheme:
  1. Standard increment: Minor versions 0-7 increment normally (e.g., 1.5 → 1.6)
  2. Rollover at 8: When minor version is 8, it rolls over to the next major version with minor 0 (e.g., 2.8 → 3.0)

​
Examples

import { avanzarVersion } from './utils/change-version';

// Standard minor version increment
const newVersion = avanzarVersion("1.5");
console.log(newVersion); // "1.6"

const anotherVersion = avanzarVersion("2.0");
console.log(anotherVersion); // "2.1"

​
Edge Cases

Version 8 Rollover: The function treats minor version “8” as the maximum before rolling over to the next major version. This creates a 0-8 range (9 possible minor versions) rather than the traditional 0-9 range.
import { avanzarVersion } from './utils/change-version';

// Starting from 0
avanzarVersion("0.0"); // "0.1"
avanzarVersion("0.8"); // "1.0"

// Large version numbers
avanzarVersion("99.7"); // "99.8"
avanzarVersion("99.8"); // "100.0"

// Sequential through rollover boundary
avanzarVersion("5.7"); // "5.8"
avanzarVersion("5.8"); // "6.0"
avanzarVersion("6.0"); // "6.1"

​
Implementation Details

The function uses string splitting and parsing to handle version numbers:
  1. Splits the version string on the ”.” delimiter
  2. Checks if the minor version equals “8” (string comparison)
  3. If yes: increments the major version and sets minor to 0
  4. If no: keeps the major version and increments the minor version
The function expects well-formed version strings with exactly one decimal point. It does not include input validation, so ensure version strings follow the “major.minor” format.
