the string index method is usually used for string operations, but how can it be implemented internally, the specific algorithm is not clear. As I met the previous article about string search on the Internet, the author provided a search idea and

var a = "Hello world";if (A.indexof ("Lo") >= 0) {//TrueFind a match}if (A.indexof ("xo") = =-1) {//TrueNo matches found}>= 0 and = = 1 This is not very good, called "abstract leakage", meaning that the code exposes the underlying implementation
