How to Remove Spaces from a String in TypeScript ?

Typescript allows us to remove the spaces between the characters or the entire words of the string. The combination of various inbuilt functions can be implemented to remove the spaces from the string. In Typescript, removing spaces from a string can be done using various approaches which are as follows:

Using split() and join() methods

The split() method mainly divides the string into the array of substrings and join(‘ ‘) then concatenates the substrings by removing the spaces from the string.

Syntax:

let outputString: string = inputString.split(' ').join('');

Example: The below example removes spaces from the inputString by splitting it into an array at each space using split(‘ ‘) and then joining the array elements into a single string without spaces using join(”), resulting in the output “GeeksforGeeks”.

Javascript

let inputString: string = "Geeks for Geeks";
let outputString: string = inputString.split(" ").join("");
console.log(outputString);

Output:

GeeksforGeeks

Using replace() method

The replace() method with the (‘ / /g) replaces all the occurnces of spaces within an empty string, which elimiates the spaces from the original string.

Syntax:

let outputString: string = inputString.replace(/ /g, '');

Example: The below example removes spaces from the inputString using the replace(/ /g, ”) method.

Javascript

let inputString: string = "Geeks for Geeks";
let outputString: string = inputString.replace(/ /g, "");
console.log(outputString);

Output:

GeeksforGeeks

Using RegExp

The regular expression with the replace() method replaces one ore more whitespace characters with an empty string by removing the spaces from the original string.

Syntax:

let outputString: string = inputString.split(/\s+/).join('');

Example: The below example removes spaces from the inputString using regular expression (/\s+/), splitting it into an array at one or more whitespace characters and then joining the array elements into a single string without spaces using join(”).

Javascript

let inputString: string = "Geeks for Geeks";
let outputString: string = inputString.split(/\s+/).join("");
console.log(outputString);

Output:

GeeksforGeeks

Using filter() method

The filter() method along with split() and join(‘ ‘) method constructs the new array of characters by exclusing the spaces. Using the join(‘ ‘) method the charcaters are contatenated back into the single string.

Syntax:

let outputString: string = inputString.split('').filter(char => char !== ' ').join('');

Example: The below example removes spaces from the inputString using the filter() method along with split(”) and join(”). It splits the string into an array of characters, filters out the space characters, and then joins the remaining characters back into a single string, resulting in the output “GeeksforGeeks”.

Javascript

let inputString: string = "Geeks for Geeks";
let outputString: string = inputString
  .split("")
  .filter((char) => char !== " ")
  .join("");
console.log(outputString);

Output:

GeeksforGeeks
