substring method

//substring() is similar to slice().
//The difference is that start and end values less than 0 are treated as 0 in substring()

let str = "Apple, Banana, Kiwi";
let part = str.substring(7, 13);

// >> Banana

console.log(str.substring(1, 3));
// expected output: "oz"

console.log(str.substring(2));
// expected output: "zilla"

substring

var str = "Some String";

public string Substring(int startIndex);

var valueOfSubstring = str.Substring(5);

public string Substring(int startIndex, int length);

var valueOfSubstring = str.Substring(5, 3);

string substring

string a = "String";
string b = a.Replace("i", "o"); // Strong
       b = a.Insert(0, "My ");  // My String
       b = a.Remove(0, 3);      // ing
       b = a.Substring(0, 3);   // Str
       b = a.ToUpper();         // STRING
int    i = a.Length;            // 6

substr method

substring

# To find the index of a substring in another string
# Take for instance, below take two strings: str and substr. 

str="hello world"
substr="world"
 
prefix=${str%%$substr*}
index=${#prefix}
 
if [[ index -eq ${#str} ]];
then
    echo "Substring is not present in string."
else
    echo "Index of substring in string : $index"
fi
