How to extract all the substrings between single quotation marks in Node.js

Answer 1

function extractSubstrings(s) {
    // Regular expression pattern to find substrings between single quotation marks
    const pattern = /'(.*?)'/g;
       
    // Find all matches in the input string
    const substrings = [];
    let match;
       
    while ((match = pattern.exec(s)) !== null) {
        substrings.push(match[1]);
    }
       
    if (substrings.length === 0) { 
        return "";
    }
          
    return substrings;
}
 
const str = "Node.js is a 'cross-platform', 'open-source' 'JavaScript runtime' environmen";
 
const result = extractSubstrings(str);
console.log(result);
 
 
 
/*

[ 'cross-platform', 'open-source', 'JavaScript runtime' ]
