Hey there! I'm currently working on extracting values that are inside curly braces "{value}". Do you think the regular expression [^{}]+(?=}) I am using is correct?
let url = "/{id}/{name}/{age}";
let params = url.match('[^{\}]+(?=})');
if(params != null){
params.forEach(param => {
console.log(param);
});
}
// expected output
id
name
age
//actual output
id
Normally, the search stops after finding the first match.
To ensure you find all matches, use a regex literal enclosed in slashes (e.g., /regex/) instead of a string enclosed in quotes (e.g., 'string').
Additionally, remember to include the /g flag at the end of your regex pattern. This flag indicates a "global" search, allowing it to scan through the entire string and identify all matches.
let url = "/{id}/{name}/{age}";
let params = url.match(/[^{\}]+(?=})/g);
// ^ do a global search
if(params != null){
params.forEach(param => {
console.log(param);
});
}For more information, visit MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions
The "g" flag in the regular expression options triggers a global search, scanning the entire string for and retrieving all matches.
