Not only that, but its in a useful form in the most common client platforms today (browser, and flash ! - of a fashion). In many cases javascript is fullfilling the promises of lisp. Complete with REPL on the client platform itself (firebug, for instance). May not be what you expect, but its there, its its not too shabby.

in the browser, javascript's REPL is essentially the address bar. you can type in javascript:alert(2+2) to output 4, or javascript:void(code) just to run an expression and swallow the output. to evaluate expressions more complex than a one liner you can inline a function, javascript:alert((function(){var x = 2; return x+x;})()). that's how bookmarklets work.

  For a more psychadelic version, try this: javascript:R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin(Rx1+ix2+x3)x4+x5; DIS.top=Math.cos(Ry1+iy2+y3)y4+y5}R++}setInterval('A()',5); void(0); (in address bar)

    the auto-formatting swallowed the multiplication symbols. the actual code should be this, with "TIMES" replaced by the multiplication symbol. is there any way to escape them? javascript: R=0; x1=.1; y1=.05; x2=.25; y2=.24; x3=1.6; y3=.24; x4=300; y4=200; x5=300; y5=200; DI=document.images; DIL=DI.length; function A(){for(i=0; i-DIL; i++){DIS=DI[ i ].style; DIS.position='absolute'; DIS.left=Math.sin(R TIMES x1+i TIMES x2+x3) TIMES x4+x5; DIS.top=Math.cos(R TIMES y1+i TIMES y2+y3) TIMES y4+y5}R++};setInterval('A()',5); void(0);
