我的代码在字符串和变量之间添加空格？ 为什么这样做呢？

Question

So when I execute this code, it adds a space between names[i] and the string?

var names = ["Bob", "Daniel", "John", "Jimmy", "Joseph"]

for (var i = 0; i < names.length; i ++) {
    console.log("I know someone called",names[i])
}

I'm new to this.

That's just the behaviour of console.log . Each parameter you pass will be separated by a space, and is expected (see here ) - if you don't want the space, try:

console.log("I know someone called" + names[i]);

By using the + , you are directly concatenating the strings and ensuring there is no space
