Remove matching entries from an array

[Rakshanda Kunte]

Hi All,

Requirement:

I have 2 arrays.

array1 = ['Software', 'Hardware', 'Service Catalog']

array2 = ['Technology', 'Governance', 'Hardware', 'HR', 'Service Desk', 'Service Catalog', 'Software']

If whatever present in array1, is matching the names in array 2, then remove those names from array 2 and give the new array.

Output should be:

array2 = ['Technology', 'Governance', 'HR', 'Service Desk']

Kindly, help with scripting.

Hello @Rakshanda Kunte 

Please use below code -

var array1 = ['Software', 'Hardware', 'Service Catalog'];
var array2 = ['Technology', 'Governance', 'Hardware', 'HR', 'Service Desk', 'Service Catalog', 'Software'];

var newArray2 = [];
for (var i = 0; i < array2.length; i++) {
    var element = array2[i];
    if (array1.indexOf(element) === -1) {
        newArray2.push(element);
    }
}
array2 = newArray2;
gs.info(array2);

Or

var arrayUtil = new ArrayUtil();

var array1 = ['Software', 'Hardware', 'Service Catalog'];

var array2 = ['Technology', 'Governance', 'Hardware', 'HR', 'Service Desk', 'Service Catalog', 'Software'];

var newArray2 = [];

array2 = newArray2;

var n = arrayUtil.diff(array1, array2);

gs.info(n);

Thanks @Maik Skoddow.

Can you also pleas help on 'how to get count of how many groups we have in an array'?

Hello @Rakshanda Kunte 

Use this for count-

var arrayUtil = new ArrayUtil();
var array1 = ['Software', 'Hardware', 'Service Catalog'];
var array2 = ['Technology', 'Governance', 'Hardware', 'HR', 'Service Desk', 'Service Catalog', 'Software'];
var newArray2 = [];
array2 = newArray2;
var n = arrayUtil.diff(array1, array2);
var count = n.length;
gs.info(count);

Hi @Rakshanda Kunte ,

You can use the ArrayUtil - Global API to achieve your requirement.

var array1 = ['Software', 'Hardware', 'Service Catalog'];
var array2 = ['Technology', 'Governance', 'Hardware', 'HR', 'Service Desk', 'Service Catalog', 'Software'];

var output = new ArrayUtil().diff(array2, array1);
gs.info(output );

In order to count the elemnts in each array you can use the below:

var array1 = ['Software', 'Hardware', 'Service Catalog'];
var array2 = ['Technology', 'Governance', 'Hardware', 'HR', 'Service Desk', 'Service Catalog', 'Software'];

var result = new ArrayUtil().diff(array2, array1);
gs.info(array1.length);
gs.info(array2 .length);
gs.info(result .length);

Please mark this as correct answer and helpful if it resolved, or mark this helpful if this help you to reach towards solution.
