detect differences between two strings with Javascript

由 主宰稳场 提交于 2019-11-27 08:39:07
With Javascript, I want to check how many differences there are between two strings. Something like: var oldName = "Alec"; var newName = "Alexander"; var differences = getDifference(oldName, newName) // differences = 6 Any letters added to the name should count as one change per letter. Changing a letter should count as a change per letter. Swaping two letters should count as two changes as your really changing each leter. However, shifting a letter and inserting another should only count as one change. For example: Changing "Alex" to "Alexander" would be 5 changes as 5 letters have been added
