1. Create a string variable and assign a value to it.
2. Use the slice() method to remove the last character from the string.
3. Assign the new value to the same variable.

    let myString = "Hello World!";
    myString = myString.slice(0, -1);
    console.log(myString);
    // Output: "Hello World"

Method 2: Using the substring() method#
