js字符串处理之绝妙的代码

function uniqStr(str) {
 var str = str.split('');
 var zarr = [];
 for (var i = 0; i < str.length; i++) {
 if (zarr.indexOf(str[i]) === -1) {
 zarr.push(str[i])
 }
 }
 return str.join('')
}

function sc(str) {
 var obj = {
 r: "s",
 o: "i",
 t: "c",
 n: "u",
 F: "a"
 };
 var g = Object.keys(obj).concat(Object.values(obj));
 var str = str.split('/');
 var sr = '';
 for (var i = 0; i < str.length; i++) {
 sr = sr + g[str[i]];
 }
 return sr;
}
sc("4/8/3/7/2/6/1/3");//"constructor"
sc("7/1/3/5/2/0/8/7/2/1/0")//"Function"

var str = "abcdef";
var a = str.split('');
var b = [];
var c = [];
for (var i = 0; i < a.length; i++) {
 if (i % 2 === 0) {
 b.push(a[i]);
 } else {
 c.push(a[i]);
 }
}

function jiou(b, c) {
 var b = b.split('');
 var c = c.split('');
 var m = [];
 for (var i = 0; i < b.length; i++) {
 m.push(1 + i * 2);
 }
 for (var j = 0; j < c.length; j++) {
 b.splice(m[j], 0, c[j])
 }
 return b.join('');
 };
