Example 1: Using split() and join()
// program to trim a string
const string = ' Hello World ';
const result = string.split(' ').join('');
console.log(result);
Output
HelloWorld
In the above program,
- The
split(' ')method is used to split the strings into individual array elements.["", "", "", "", "", "", "Hello", "World", "", "", "", "", "", "", ""]
- The
join('')method merges the array into a string.
Example 2: Using Regular Expression
// program to trim a string
function trimString(x) {
const result = x.replace(/\s/g,'');
return result
}
const result = trimString(' Hello World ');
console.log(result);
Output
HelloWorld
In the above program, the Regular Expression is used with the replace() method to remove all whitespaces from a text.
/\s/g checks for whitespace in the string.
