RegExp for expression sourrounded by special characters-CodePudding

Is there a way to use RegExp to replace a substring surrounded by '/*' on the left, and '*/' on the right. The substring can include anything (numbers, underscore, special characters)

var string = "abc /*abcd_^&^djh:*/ <-abcd_.";

function replace(string, regexp, replacement="") {
    return string.replaceAll(new RegExp(regexp), replacement);
}

let regexpReplacement; //The RegExp for a substring surounded by "/*" and "*/"

console.log(replace(string, regexpReplacement));
//Should output "abc  <-abcd_."

CodePudding user response：

Perfect time to use a lazy 0-unlimited quantifier.

Basically:

Match /*, then anything as lazily as possible (with *?) so that the next */ won't be absorbed, then */. The global flag allows replaceAll to work.

var string = "abc /*abcd_^&^djh:*/ <-abcd_.";

function replace(string, regexp, replacement="") {
    return string.replaceAll(new RegExp(regexp), replacement);
}

let regexpReplacement = /\/\*.*?\*\//g;

console.log(replace(string, regexpReplacement));
//Should output "abc  <-abcd_."
