Benchmark of efficient Javscript string replacement function

This is a frequently used HTML special character replacement function, that is, replacing &, <, >, " and other functions with &, <, >, ". The usual practice is to use several replace functions in succession, but Clear only uses one replace to complete the replacement.

I benchmarked these two functions and found that the efficiency of the new function is about 1.4 times that of the original function. Although it is not as efficient as expected, when there are more strings to be replaced, the efficiency should improve.

The test method is to execute two functions 100 times on a 2048-byte long string, and take the execution time. Below are the results of 10 tests. toTXT_1 is the usual method, and toTXT_2 is the Clear method.

toTXT_1(ms)	toTXT_2(ms)	toTXT_1/toTXT_2
1609	1204	75%
2250	1547	69%
1672	1313	79%
1813	1250	69%
1844	1219	66%
2063	1421	69%
2031	1172	58%
1797	1360	76%
2015	1281	64%
1860	1500	81%
