How to use String.split() and Array.join() Method In Javascript

Using Array.reduce() method:

This method involves using split() to break the string at each target substring and then using join() to reassemble the string with the new substring in place of the target substrings.

Example: In this example, we will replace multiple substrings using split() and join() methods.

JavaScript

let str = "I have a Lenovo Laptop, a Honor Phone, and a Samsung Tab.";
let replacements = {
    "Lenovo": "Dell",
    "Honor": "OnePlus",
    "Samsung": "Lenovo"
};

function replaceMultiple(str, replacements) {
    for (let [oldStr, newStr] of Object.entries(replacements)) {
        str = str.split(oldStr).join(newStr);
    }
    return str;
}

console.log(replaceMultiple(str, replacements));

Output

I have a Dell Laptop, a OnePlus Phone, and a Lenovo Tab.
