Slicing can best be described as
1). assigning a value to a variable
2). combining two or more strings to form one big string
3). pulling out one specific character from a string
4). pulling out groups of characters from a string

Option 4 : Pulling out groups of characters from a string.

Explanation:

            string.slice(start, end)

For example:

Extract the characters from position 3 to 8:

                 var str = "Hello world!";

                 var res = str.slice(3, 8);

ok that sounds like a app that my brother would like

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
