What is jQuery's Equivalent of str_replace in JavaScript?

In JavaScript, the equivalent of PHP’s str_replace is the replace method of strings. While jQuery doesn't offer a direct str_replace equivalent, JavaScript’s replace and replaceAll methods can be used effectively.

1. Replace a Single Instance with replace

• This method replaces the first occurrence of a substring.
• replace("world", "JavaScript") replaces the first occurrence of "world" with "JavaScript."
• Works for single, non-repeated replacements.

const original = "Hello, world!";
const result = original.replace("world", "JavaScript");
console.log(result);

Hello, JavaScript!

2. Replace All Instances with replaceAll

• For multiple replacements, use replaceAll (introduced in ES2021).
• replaceAll("world", "universe") replaces all occurrences of "world."
• This method is straightforward for global replacements without regular expressions.

const original = "Welcome to the world of JavaScript. Explore the world!";
const result = original.replaceAll("world", "universe");
console.log(result); 

Welcome to the universe of JavaScript. Explore the universe!

3. Using Regular Expressions for Global Replacement

• For broader compatibility, use replace with a regular expression.
• /world/g is a regular expression to match all occurrences of "world."
• The g flag ensures all matches are replaced.

const original = "The world is vast. The world is beautiful.";
const result = original.replace(/world/g, "universe");
console.log(result); 

The universe is vast. The universe is beautiful.
