The difference between JS string indexof and search method

1.indexof method

The IndexOf () method returns the position of the first occurrence of a specified string value in a string.

Grammar:

Note: There are optional parameters (that is, the location where the settings begin).

2. Search method

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

Note: The s-earch method can find the specified string based on a regular expression (it can ignore the case and does not perform a global retrieval), and there is no optional parameter (that is, where the setting starts).
