Trimming a String at the Beginning
In this case, we trim the string at the beginning using the trimLeft() function.
JavaScript trimLeft() Function: This method is used to eliminate white space at the beginning of a string. The string’s value is not changed in any way, if any white space is present after the string, it’s not modified.
Syntax:
string.trimLeft();
Example 1: In this example, a variable var is declared with the string ” w3wiki”. Notice the given string that has whitespace at the left end. The trimLeft() function will remove the whitespace at the beginning.
Javascript
const word = " w3wiki";console.log("Initial String:" + "'" + word + "'");// Trimming the string at the Beginning let new_word = word.trimLeft();console.log("Modified String:" + "'" + new_word + "'"); |
Initial String:' w3wiki' Modified String:'w3wiki'
Example 2: In this example, a variable var is declared with the string ” w3wiki “. Notice the given string that has whitespace at both ends. trimLeft() will only remove the whitespace at the beginning and leaves the whitespace at the end unchanged.
Javascript
const word = " w3wiki ";console.log("Initial String:" + "'" + word + "'");// Trimming the string at the startlet new_word = word.trimLeft();console.log("Modified String:" + "'" + new_word + "'"); |
Initial String:' w3wiki ' Modified String:'w3wiki '
