How to check if a string starts with a substring from an array of substrings in Node.js

Answer 1

function startsWithAny(string, substrings) {
    for (const substring of substrings) {
        // Use startsWith to check if the string starts with the substring
        if (string.startsWith(substring)) {
            return true;
        }
    }
    return false; // Return false if no substring matches
}

const string = "nodejs";
const substrings = ["xy", "poq", "xzp", "mnop", "nod", "rsuvw"];

// Check if the string starts with any substring from the array
if (startsWithAny(string, substrings)) {
    console.log("The string starts with a substring from the array.");
} else {
    console.log("The string does not start with any substring from the array.");
}



/*
run:

The string starts with a substring from the array.
