Get version number from String in Javascript?

Question

I have a version number with 3 digits as a String,

var version = "1.2.3";

and would like to compare it to another version. To see if version is newer than otherversion,

var otherVersion = "1.2.4";

How would you do it?

Answer 1

Pseudo:

• Split both on .
• Compare parts sequentially: Major -> Minor -> Rev (if part exist for both versions).
• If oV[n] > v[n]: oV is greatest.
• Else: Compare next subpart.
