Hey there, I'm attempting to extract the word right before a comma in a sentence.
For instance, consider the following string:
"Cloudy, and 51 ° F "
I aim to retrieve CLOUDY as the output.
Could someone guide me on how to achieve this using regex and javascript? I understand that the .match command in javascript should be used. Thank you in advance for any assistance provided.
In addition to the solution using `split` mentioned in the discussion, I have another approach.
Here is a straightforward regex pattern that can be used:
\S+(?=,)
You can see a working example here. Essentially, this regex expresses a sequence of non-whitespace characters followed by a comma.
To implement this in JavaScript:
var str = "Mostly cloudy, and 51 ° F";
var matches = str.match(/\S+(?=,)/g); // matches = ["cloudy"]
The variable matches will hold an array of words preceding commas in the string str. If you only require the first match, simply omit the g flag.
