How To Split String With Length In Javascript

In Javascript, splitting a string can be done using the split() method. However, sometimes we want to split a string into smaller sections based on a specific length. In this tutorial, we will be discussing how to split a string with a specific length using Javascript.

Steps:

1. First, we need to define the string that we want to split with a specific length. Let’s take the string “Hello world!” as an example.

2. Next, we need to define the length that we want to split the string with. Let’s say we want to split the string into sections of 3 characters.

3. We can use a for loop to iterate over the string and split it based on the defined length. In each iteration, we can use the substring() method to extract a section of the string with the defined length.

4. We can store each extracted section in an array using the push() method.

5. After the for loop completes, we will have an array of string sections based on the defined length. We can then output this array to the console or display it on the webpage using the join() method.

Here is the complete code for splitting a string with a specific length in Javascript:

1
2
3
4
5
6
7
let myString = "Hello world!";
let stringLength = 3;
let stringArray = [];
 
for (let i = 0; i < myString.length; i += stringLength) {                        stringArray.push(myString.substring(i, i + stringLength));
}
console.log(stringArray.join(", "));

This will output the following array:

[
   "Hel", 
   "lo ", 
   "wor", 
   "ld!"
]

Conclusion

Splitting a string with a specific length in Javascript can be achieved using a for loop and the substring() and push() methods. This method is useful when we want to break down a long string into smaller sections for ease of use or display purposes.
