157. semver compare

Here's one possible solution using basic string manipulation and comparison:

function compare(version1, version2) {
  const parts1 = version1.split('.');
  const parts2 = version2.split('.');
  for (let i = 0; i < 3; i++) {
    const num1 = parseInt(parts1[i]);
    const num2 = parseInt(parts2[i]);
    if (num1 > num2) {
      return 1;
    } else if (num1 < num2) {
      return -1;
    }
  }
  return 0;
}

Explanation:

• The function takes in two semver strings, version1 and version2.
• Each semver string is split into an array parts based on the period separator.
• For each part (up to the third), it is converted to an integer using parseInt().
• If the current part of version1 is greater than that of version2, we return 1.
• If the current part of version1 is less than that of version2, we return -1.
• If we reach the end of the loop without returning, it means the two versions are equal, so we return 0.
