trimStart < String < JavaScript

The trimStart() of a String removes whitespace from the beginning of the string and returns a new string without modifying the original string.

    
    const greeting = '   Hello world!   ';

    const greetingTrimStart = greeting.trimStart();

    console.log(greetingTrimStart);
    // "Hello world!     ";

    console.log(greeting);
    // "   Hello world!   ";
