Simple Example of string inversion JavaScript programming

Let's first look at the array inversion.

Array inversion method in JavascriptProgramming LanguageIs: the name of the array to be reversed. Reverse ();.

CodeAs follows:

VaR A = []; for (VAR I = 0; I <9; I ++) {A [I] = I + 1;}. reverse (); console. log ();

The above "standard" Writing Method is too simple. If you do not need the reverse () method:

VaR arr = [1, 54, 3, 8]; var L = arr. length; var temp; For (VAR I = 0; I <l/2; I ++) {temp = arr [I]; arr [I] = arr [l-i-1]; arr [l-i-1] = temp ;}

In practice, strings are more involved. below is the code for string inversion:

VaR arr = '000000'; var L = arr. length; arr = arr. Split (''); var temp; For (VAR I = 0; I
