In this example, we declare a variable called char inside the for.of loop that represents each character of the string. Loop through the string with for.of loop To loop through a string using a for.of loop, you simply declare a variable that represents each character of the string and then use the loop to iterate through the string. This loop is designed specifically for iterating over iterable objects, such as arrays, maps, and strings. Loop Through a String using For…of LoopĪnother commonly used approach to loop through a string is to use the for.of loop. To get the length of the string, we use its length property.Ģ. The loop continues until the counter variable reaches the length of the string. In this method, we use a counter variable that starts from 0, and increments by 1 in each iteration.
The for loop will iterate through the string one character at a time, starting from the first character and ending at the last. The most common way to loop through a string in JavaScript is to use a regular for loop. Loop Through a String using a Regular For Loop

To define a string in JavaScript, you can use single quotes( ''), double quotes( ""), or backticks( ``).įor example: // Different ways of defining a string in JavascriptĬonst str1 = 'This is a string using single quotes.' Ĭonst str2 = "This is a string using double quotes." Ĭonst str3 = `This is a string using backticks.` Īll three ways of defining a string are equivalent in JavaScript, so it’s mostly a matter of personal preference which method you want to use. It can be any combination of letters, numbers, special characters, and whitespace enclosed in quotation marks. In JavaScript, a string is a sequence of characters that represent textual data.
