Use RegExp-literals, a look-ahead and [A-Z]:
使用 RegExp-literals、前瞻和[A-Z]：
"HiMyNameIsBob".split(/(?=[A-Z])/).join(" "); // -> "Hi My Name Is Bob"

You can use String.match to split it.
您可以使用 String.match 来拆分它。
"HiMyNameIsBob".match(/[A-Z]*[^A-Z]+/g)
// output
// ["Hi", "My", "Name", "Is", "Bob"]
If you have lowercase letters at the beginning it can split that too. If you dont want this behavior just use +instead of *in the pattern.
如果开头有小写字母，它也可以拆分。如果您不想要这种行为，只需在模式中使用+而不是*。
"helloHiMyNameIsBob".match(/[A-Z]*[^A-Z]+/g)
// Output
["hello", "Hi", "My", "Name", "Is", "Bob"]

The solution for a text which starts from the small letter -
从小写字母开始的文本的解决方案 -
let value = "getMeSomeText";
let newStr = '';
for (var i = 0; i < value.length; i++) {
if (value.charAt(i) === value.charAt(i).toUpperCase()) {
newStr = newStr + ' ' + value.charAt(i)
} else {
(i == 0) ? (newStr += value.charAt(i).toUpperCase()) : (newStr += value.charAt(i));
}
}
return newStr;

To expand on Rob W's answer.
扩展 Rob W 的回答。
This takes care of any sentences with abbreviations by checking for preceding lower case characters by adding [a-z], therefore, it doesn't spilt any upper case strings.
这通过添加 来检查前面的小写字符来处理任何带有缩写的句子[a-z]，因此，它不会溢出任何大写字符串。
// Enter your code description here
var str = "THISSentenceHasSomeFunkyStuffGoingOn. ABBREVIATIONSAlsoWork.".split(/(?=[A-Z][a-z])/).join(" "); // -> "THIS Sentence Has Some Funky Stuff Going On. ABBREVIATIONS Also Work."
console.log(str);
