bash - Splitting a comma separated string into multiple words so that I can loop through each word -

I want to split the string to use with for-loop in Bash. For example, I have this string

  Hello, mine, name, is, Mania   
 and I want to divide it in different words So that I can loop through every word, can someone help me?   
 
 
 Using a word segmentation in the array is a very easy way:  <<>  S = "hello, mine, name, is, brain"   
 You set the input field separator to:  
  IFS =, < / Code>  
 and then you split the string into an array:  
  a = ($ s)   
 Result:  
  for word in "$ {a [@]}"; Do echo "- [$ word]"; Done
