You should use substring  not jQuery  to do this   Try something like this   member substring member length - 2  member length    W3Schools  not official  but occasionally helpful     http   www w3schools com jsref jsref substring asp  Adding MDN link as requested by commenter  https   developer mozilla org en JavaScript Reference Global Objects String substring

Slice can be used to find the substring  When we know the indexes we can use an alternative solution like index wise adder  Both are taking roughly the same time for execution   x000D   x000D  const primitiveStringMember    my name is Mate    const objectStringMember   new String  my name is Mate    console log typeof primitiveStringMember    string console log typeof objectStringMember    object      However when we use   operator to string primitive type  JS will wrap up the string with object  That s why we can use the methods String object type for the primitive type string        Slice method const t0   performance now    slicedString   primitiveStringMember slice -2    te const t1   performance now    console log  Call to do slice took   t1 - t0  milliseconds         index vise adder method const t2   performance now    length   primitiveStringMember length neededString   primitiveStringMember length-2  primitiveStringMember length-1    te const t3   performance now    console log  Call to do index adder took   t3 - t2  milliseconds     x000D   x000D   x000D

The following example uses slice   with negative indexes   x000D   x000D  var str    my name is maanu    x000D  console log str slice -3           returns  nu   last two x000D  console log str slice 3  -7       returns  name is  x000D  console log str slice 0  -1        returns  my name is maanu  x000D   x000D   x000D

EDIT   2020  use string slice -2  as others say - see below   now 2016 just string substr -2  should do the trick   not substring      taken from MDN     Syntax      str substr start   length        Parameters      start      Location at which to begin extracting characters  If a negative number is given  it is treated as strLength   start where strLength is   the length of the string  for example  if start is -3 it is treated as   strLength - 3   length       Optional  The number of characters to extract    EDIT  2020  MDN says     Warning  Although String prototype substr      is not strictly   deprecated  as in  removed from the Web standards    it is considered   a legacy function and should be avoided when possible  It is not part   of the core JavaScript language and may be removed in the future

You can pass a negative index to  slice    That will indicate an offset from the end of the set  var member    quot my name is Mate quot    var last2   member slice -2    alert last2       quot te quot

Shortest  str slice -2   Example   x000D   x000D  const str    test   const last2   str slice -2    console log last2   x000D   x000D   x000D
