The split method breaks a collection into the given number of groups.

The concat method appends the given array or collections values onto the end of. In the output, we can see that the splitting only happens twice. The limit parameter limits the number of splits to 2 because we are defining 2 as the value of the limit. In this example, we have used a regular expression for the delimiter so that we can split the string into words delimited by spaces. The split () function will create an array of strings by splitting the given string wherever the given letter o occurs until the limit is reached.

This function returns the output in array form. We have then invoked the split() method of the totn_string variable to break the string into an array of strings using a delimiter. The split () function is a string function of Node.js which is used to split string into sub-strings.

Browser Automation Studio supports arbitrary javascript execution. Note that the result array may have fewer entries than the limit in case the split () reaches the end of the string before the limit. If the limit is 1, the split () returns an array that contains the string. If the limit is zero, the split () returns an empty array.
