How to use slice and stitch methods In Javascript
It is the basic way to realize the solution to this problem. Visit each character of the string and slice them in such a way that it removes the newline and carriage return characters.
Code snippet:
let newstr = "";
for (let i = 0; i < str.length; i++)
if (!(str[i] == "\n" || str[i] == "\r"))
newstr += str[i];
All this code snippet does is just copy all the characters that are not “newline” or “carriage return” to another variable. However, there are a lot of overheads in this solution, and therefore not an optimal way to remove newlines.
Example: This example shows the removal of all line breaks from the given string.
// Input string
str = "Hello \nWelcome \nto \nw3wiki"
// Display Input string
console.log(str)
// Function to remove line breaks
function remove_linebreaks_ss(str) {
let newstr = "";
// Looop and traverse string
for (let i = 0; i < str.length; i++)
if (!(str[i] == "\n" || str[i] == "\r"))
newstr += str[i];
console.log("new string : "+newstr);
}
// Function call
remove_linebreaks_ss(str);
Output
Hello Welcome to w3wiki new string : Hello Welcome to w3wiki
How to remove all line breaks from a string using JavaScript?
Line breaks in strings vary from platform to platform, but the most common ones are the following:
- Windows: \r\n carriage return followed by a newline character.
- Linux: \n just a newline character.
- Older Macs: \r just a carriage return character.
There are two methods to accomplish this task. One of the ways is by using a traditional programming loop and visiting every character one at a time. Another is using Regular Expressions.
