1.indexof method

indexOf() method can return the position where a specified string value first appears in the string.

Syntax:

Note: There are optional parameters (that is, setting the starting search position) .

2. Search method

The search() method is used to retrieve the specified substring in the string, or search with a regular expression matching substring.

Note: The search method can search for the specified string based on a regular expression (can ignore case, and does not perform a global search), At the same time, there are no optional parameters (that is, setting the starting search position).
