Syntax:
tickStep(start,stop,count);
Parameters: This function accepts three parameters as mentioned above and described below:
- start: It is the starting value from where we want the array element to be, it is inclusive.
- stop: It is the starting value to which we want the array element to be, it is inclusive.
