I will code in jа vascript;

function findFirstComma () {

var pos;

var line = 'Thi, s is a t, est';

var clause;

pos = line. indexOf (','); / /set pos in 3.

clause = line. slice (0, pos); / / saves in clause the value 'Thi'.

}

Explanation:

The slice (start, end) method extract a part of a string then returns a new string with the extracted part. The end parameter indicates where to end the extraction (up to, but not including).

The includes (value) method determines if a string contains the characters on a specified string, if it doesn't match then returns - 1.
