Javascript 字符串比较返回false

为什么这一直都是假的

var a = new String("17-0069,,Alex Libengood,Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC,Site inspection,,0.55,/mile,0,miles,,1,17-0069><><Alex Libengood><Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC><Site inspection><0.55><1,Mileage").trim();
var b = new String("17-0069,,Alex Libengood,Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC,Site Inspection,,0.55,/mile,0,miles,,1,17-0069><><Alex Libengood><Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC><Site Inspection><0.55><1,Mileage").trim();
if (a === b){
   return true;
} else {
   return false;
}

var a=new String（“17-0069，Alex Libengood，从-Meadors办公室到-201 Hildebrand Dr，Bonneau SC，现场检查，0.55，/mile，0，miles，1,17-0069的行程，”
是同一根线

不，不是。仔细看：

"17-0069,,Alex Libengood,Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC,Site inspection,,0.55,/mile,0,miles,,1,17-0069><><Alex Libengood><Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC><Site inspection><0.55><1,Mileage"
"17-0069,,Alex Libengood,Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC,Site Inspection,,0.55,/mile,0,miles,,1,17-0069><><Alex Libengood><Travel from - Meadors Office - to - 201 Hildebrand Dr, Bonneau SC><Site Inspection><0.55><1,Mileage"
                                                                                                ^                                                                                                                                    ^

字符串的字符是相同的，但这些字符存储在不同的字符串对象中，而这些字符串对象并不相同。@RandyCasburn否，
trim（）
不返回对象，因为字符串是不同的！一定有一些不可见的字符/不同的编码。@Bergi-我没有滚动：-/不要用
字符串
构造函数创建字符串。没有必要这样做。好吧，这很尴尬：0我想我检查了15次，但仍然没有看到它。c不过，检查ode代码片段是个好主意。谢谢@Bergi！
for (let i=0; i<255; i++) if (a[i] != b[i]) console.log(i, a[i], b[i])
