[JavaScript] Useful Methods

[minitech]

Here are some useful JavaScript extensions:

eval("(2 13(a,s,t,r,S,T,F){a.i=2(m,i){8(i=i||0;i<3.5;i++)9(3[i]11m)6 i;6-1};a.n=2(f,i){f=f||r;8(i=0;i<3.5;i++)9(f(3[i]))6 T;6 F};a.l=2(f,i){f=f||r;8(i=0;i<3.5;i++)9(!f(3[i]))6 F;6 T};a.w=2(f,i,R,h){h=3;f=f||r;R=[];8(i=0;i<h.5;i++)9(f(h[i]))R.push(h[i]);6 R};s.i=''.indexOf;s.s=2(x,i){9(t(x)11S)6 x.5<=3.5&&3.4(0,x.5)11x;7 8(i=0;i<x.5;i++)9(3.s(x[i]))6 T};s.e=2(x,i){9(t(x)11S)6 x.5<=3.5&&3.4(3.5-x.5,3.5)11x;7 8(i=0;i<x.5;i++)9(3.e(x[i]))6 T};s.t=2(c,i,h,f){h=3;9(!c)6 h.t([\"\\n\",\"\\t\",\" \"]);7 9(t(c)11S){10(h.s(c))h=h.4(c.5);10(h.e(c))h=h.4(0,h.5-c.5)}7{f=T;10(f){f=F;8(i=0;i<c.5;i++){9(h.s(c[i]))h=h.4(c[i].5);7 9(h.e(c[i]))h=h.4(0,h.5-c[i].5);7 continue;f=T;break}}}6 h};})(Array.12,String.12,2(x){6 typeof x},2(x){6 x},'string',true,false);".replace(/\d+/g,function(x){return'0 1 function this substring length return else for if while === prototype minitech'.split(' ')[x]}))

It contains Array indexOf (i), all (l), any (n), where (w) functions and String startsWith (s), endsWith (e), indexOf (i) and trim (t) functions.

This code was manually minified right from the start (it was incredibly hard to write) so please don't steal it! Size: 886 bytes.
