复合星星图形，思路一样哈

fn1()
function fn1(){
var str = ‘’;
for(var row = 1;row < 5;row ++){
for(var star = 1;star <= row;star ++){
str += ‘’;
}
str += ‘+’;
for(star = 7;star >= 2 * row - 1;star --){
str += '’;
}
str += ’ ';
for(star = 1;star < 5;star ++){
str += ‘’;
}
for(var quo = 1;quo < 3;quo ++){
str += ‘"’;
}
for(var negation = 1;negation <= 2 * row - 2;negation ++){
str += ‘^’;
}
for(star = 1;star < 5;star ++){
str += '’;
}
str += ‘\n’;
}
console.log(str);
}
