Get numbers of difference in two strings javascript-CodePudding

i have two string

const string1 = "usa(Country), with concealed(O), zipper(Closure)"
const string2 = "usa(Country), with(O), concealed zipper(Closure)"

I want to find diff in these two string for example in this scenario it is 2

CodePudding user response：

I'm presuming the strings need to be compared based on the comma separations, but to be fair there isn't enough details in the question...

Split the strings by comma

// split function will be an array of strings
const split = (str, delimiter) => str.split(delimiter)

Apply the above function to both strings, and compare the results

// this uses lodash
// result will be an array, get the length
const result = _.difference(split(string1, ','), split(string2, ',')

If you're not going to use lodash, you can look up the vanilla JS implementation of difference

If order is important, you may need _.xor, but you can determine that with testing
