Nov 12, 2024 · The reduce() method can be used to iterate over a string by first splitting it into an array, then using the accumulator to concatenate or perform operations on each character. Syntax: string.split('').reduce((acc, char) => { // Process char return acc + char;}, '' ); JavaScript

You can now iterate over individual Unicode code points contained in a String by using String.prototype[@@iterator], which returns a value of well known Symbol type Symbol.iterator - the default iterator for array-like Objects (String in this case).

Feb 11, 2025 · The [Symbol.iterator]() method of String values implements the iterable protocol and allows strings to be consumed by most syntaxes expecting iterables, such as the spread syntax and for...of loops. It returns a string iterator object that yields the Unicode code points of the string value as individual strings.

Apr 22, 2020 · For many things in JavaScript, there’s not a single way to achieve them. A thing as simple as iterating over each character in a string is one of them. Let’s explore some methods and discuss...

Apr 10, 2025 · String.prototype[Symbol.iterator]() Returns a new iterator object that iterates over the code points of a String value, returning each code point as a String value.

May 19, 2017 · There is a direct option to iterate over a string directly: to use for...of or for...in: let text = document.getElementById('textInp').value; for(let i in text) { // Do something. console.info('i:', i, ' char: ', text[i]) use string length and iterate and replace whatever you want. yourstring= yourstring.replace(yourstring[i],"yourvalue")

Mar 27, 2016 · You can use an ordinary for loop and index into the string with []: for (var i = 0; i < strBitCount.length; ++i) if (Number(strBitCount[i]) === 1) answer++; Note that you could also just add the digit to answer :

Nov 14, 2023 · Iterating over the characters of strings is a fundamental technique in JavaScript. The built-in string iterator provides a simple way to traverse and process strings. For advanced usage, generators allow creating custom iterators with full control over iteration logic.

Dec 12, 2024 · Iterating over characters in a JavaScript string can be done efficiently using a variety of methods. From the traditional for loop to more modern for…of and array methods, each has its use cases and trade-offs.

Jan 9, 2023 · [@@iterator]() returns an iterator object which iterates over all code points of String. String[@@iterator] is a Built-in Property of String. We can use this method by making a string iterator.
