How to remove a part of all strings in an array in javascript?

I want split array value .

for example

gUser[1] = CAR.BENZ.CCLASS.1962

gUser[2] = CAR.PORSCHE.911.2001

I want get string only BENZ.CLASS.1962 and PORSCHE.911.2001

How to split array value on java script?

@update.

Something Like This

`for(let index = 0; index < gUser.length; index++) {
    console.log(gUser[index].split('.').splice(0, 1).join('.'));
}`

I haven't tested it. Please check and let me know

You can use map to access each string in array then use replace. Use a regex to match string before '.' and replace only the first match, like this:

  var gUser = ['CAR.BENZ.CCLASS.1962', 'CAR.PORSCHE.911.2001'];

  var gUserModified = gUser.map(function(v){
        return v.replace(/[^\.]+\./, '');
  });
  console.log(gUserModified);

Its easier split then shift the array to remove the first item like this:

gUser = ["CAR.BENZ.CCLASS.1962"];
var benz = gUser[0].split(".");
benz.shift();
alert(benz.join('.'));

There are other options from shift like slice(1) but In terms of performance, shift is apparently faster https://jsperf.com/shift-pop-vs-slice/4

So here is the way without using any regex by only using string and array methods. 

const gUser = ['CAR.BENZ.CCLASS.1962', 'CAR.PORSCHE.911.2001', 'XYZAB.PORSCHE.YSA.2021']

for (let i = 0; i < gUser.length; i++) {
  console.log('Required String: ', gUser[i].split('.').slice(1).join('.'));
}

What we do is, we split the string into parts where . is encountered.

gUser[0].split('.') returns ['CAR', 'BENZ', 'CCLASS', '1962']

Later when slice(1) is called, the zeroth element of array is chopped off and will return ['BENZ', 'CCLASS', '1962']

And finally using join('.'), we merge the array elements to a single string with a . between each element, which returns BENZ.CCLASS.1962

Hope this helps! :)

Split it with dot then slice it and join it with dot

var gUser =[];
gUser[1] = "CAR.BENZ.CCLASS.1962";

gUser[2] = "CAR.PORSCHE.911.2001";

console.log(gUser[1].split('.').slice(1).join('.'));
console.log(gUser[2].split('.').slice(1).join('.'));

var gUser = [];
gUser[1] = "CAR.BENZ.CCLASS.1962";
var gu1 = gUser[1].split(".");
gu1.shift();
console.log(gu1.join("."));

The below code is not tested but should probably work, with maybe minor tweaks

var splitStr = ''
var correctCarArr = []
for(let i = 0; i < gUser.length; i++){
  splitStr = gUser[i].split('.')
  let temp = ''
  for(let j = 1; j < splitStr.length; j++){
    temp += splitStr[j]
  }
  correctCarArr.push(temp)
}

From your question, it's not clear if the array is a string array

If it is a string array you can do:

ES6+: gUser.map((user)=>{return user.split("CAR.")[1]})

ES5: gUser.map(function(user){return user.split("CAR.")[1]});
