how to save an array element in a var or another array element?

Hi, i want to save an array element in a variable or another array element. or do something like the following: i have one array with indexes which is ind[]. another array op with 5 elements. i want to arrange op[] with respect to the indexes given by ind[] such that op[0] is copied oup[4], op[2] is copied to oup[3]. the positions are saved in ind[]. i tried to do it the way it is done in C but it is wrong. since i am a beginner i would really appreciate any help. the code is as follows:

var i; var jt= new Array(); jt[0]=0; var op = new Array(); op[0]=12; op[1]=14; op[2]=5; op[3]=7; op[4]=20; var ind = new Array(); ind[0]=4; ind[1]=1; ind[2]=3; ind[3]=0; ind[4]=2; var oup= new Array(); oup[0]=0; oup[1]=0; oup[2]=0; oup[3]=0; oup[4]=0;

for (i=0;i "); document.write(oup[i] + "
"); document.write("this is op " +op[i] + "
"); document.write("this is index "+ind[i] + "
"); } `
