使用正则表达式的Javascript拆分字符串

Question

I'm working in javascript and I have the following string I'd like to split using the split() function:

'{'hello', 'hi'},{'hi', 'hello'}'

Into: Array: [{'hello', 'hi'}, {'hi', 'hello'}]

My problem in doing this split is that there are other commas, and I want to split it on the particular comma between the two },{ . The regular expression I tried to use is /(?<=}).*(?={)/g , but it's giving me errors when I try to run it. Let me know which expression to use. Any help is greatly appreciated!

Answer 1

The regex you're looking for is /{(.*?)}/g and if you use it in a string.match() method, you'll get the array of {} you're looking for.

 let str = `{'hello', 'hi'}, {'hi', 'hello'}` let arr = str.match(/{(.*?)}/g) console.log(arr)
