I want to remove "I will" at the beginning of a string. Those "I will" words could be uppercase/lowercase, so I will need to match for case insensitive. But I only want to remove those words if they are at the beginning of the string.
我想在字符串的开头删除“我会”。那些“我会”的单词可能是大写/小写，所以我需要匹配不区分大小写。但是我只想删除这些单词，如果它们位于字符串的开头。
I tried .replace(), but that doesn't take into account the situations above.
我尝试过.replace（），但这没有考虑到上面的情况。

Use the ignore case flag i:
使用ignore case标志i：
var x = "I will write good code";
// the ^ at the start tells it to match from the beginning
// the i flag tells it to ignore case
x = x.replace(/^i\s+will\s+/i, '');
// Outputs: "write good code" regardless of the case of "i will"
