How to extract all the substrings between single quotation marks in JavaScript

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 = "JavaScript is a 'programming' 'language' and 'core technology' of the 'Web'";

const result = extractSubstrings(str);
console.log(result);



/*
run:

[ 'programming', 'language', 'core technology', 'Web' ]
