Is there a JavaScript strcmp

Question

Can anyone verify this for me  JavaScript does not have a version of strcmp    so you have to write out something like      str1  lt  str2                  -1                   str1  gt  str2   1   0

How about   String prototype strcmp   function s        if  this  lt  s  return -1      if  this  gt  s  return 1      return 0      Then  to compare s1 with 2   s1 strcmp s2

var strcmp   new Intl Collator undefined   numeric true  sensitivity  base    compare    Usage  strcmp string1  string2   Result  1 means string1 is bigger  0 means equal  -1 means string2 is bigger   This has higher performance than String prototype localeCompare  Also  numeric true makes it do logical number comparison

What about  str1 localeCompare str2

User · Answer

localeCompare   is slow  so if you don t care about the  correct  ordering of non-English-character strings  try your original method or the cleaner-looking   str1  lt  str2   -1     str1  gt  str2    This is an order of magnitude faster than localeCompare   on my machine   The   ensures that the answer is always numeric rather than boolean

Javascript doesn t have it  as you point out   A quick search came up with   function strcmp   str1  str2            http   kevin vanzonneveld net            original by  Waldo Malqui Silva               input by  Steve Hilder            improved by  Kevin van Zonneveld  http   kevin vanzonneveld net              revised by  gorthaur              example 1  strcmp   waldo    owald                  returns 1  1              example 2  strcmp   owald    waldo                  returns 2  -1      return     str1    str2     0       str1  gt  str2     1   -1          from http   kevin vanzonneveld net techblog article javascript equivalent for phps strcmp   Of course  you could just add localeCompare if needed   if  typeof String prototype localeCompare       undefined         String prototype localeCompare   function str  locale  options            return   this    str    0     this  gt  str    1   -1               And use str1 localeCompare str2  everywhere  without having to worry wether the local browser has shipped with it  The only problem is that you would have to add support for locales and options if you care about that
