Is there a way to extract specific text from a string using Javascript?
For example, consider the following string:
"start-extractThis-234"
The numbers at the end can vary, but the hyphens are consistent.
I believe using regex to capture the text between the two hyphens could work.
Ultimately, I am looking for the extracted result to be:
extractThis
let text = "find-thisText-567"
console.log( text.match( '-(.*)-' )[1] );
//outputs thisText
Why not simply execute
let stringToExtract = "start-extractThis-234";
let extractedString = null;
let splitString = stringToExtract.split("-");
if(splitString.length === 3){
extractedString = splitString[1];
}
Find the text between two dashes in a string that ends with numbers.
