My answer / AC

/**
 * @param {string} s
 * @param {string} t
 * @return {boolean}
 */
var isSubsequence = function(s, t) {
    var j=0;
    var tarr = t.split(""), sarr = s.split("");
    while(j<tarr.length){
        if(sarr[0] == tarr[j]) sarr.shift();
        j++;
    }
    return sarr.length===0;
};

思路：用一个队列tarr来处理要匹配的那一组字符串，然后对一整个的要匹配的文本进行遍历，看看遍历完了是否完全匹配完tarr了
