🧡 Hello All JavaScript Lovers Outhere!
Today you're going to learn about the String Object In JavaScript.
This tutorial is a series of videos, in each video we will discuss a method (or more) of the String Object in JavaScript.
In today's video, you're going to learn about the padStart, and padEnd methods.
The padStart() method pads the current string with another string (multiple times, if needed) until the resulting string reaches the given length. The padding is applied from the start of the current string.
The padEnd() method pads the current string with a given string (repeated, if needed) so that the resulting string reaches a given length. The padding is applied from the end of the current string.
🟢🟠 The string.padStart() and string.padEnd().
🔷 Syntax :
padStart(targetLength)
padStart(targetLength, padString)
padEnd(targetLength)
padEnd(targetLength, padString)
🔹targetLength : The length of the resulting string once the current str has been padded. If the value is less than str.length, then str is returned as-is.
🔹padString : The string to pad the current str with. If padString is too long to stay within the targetLength, it will be truncated from the end. The default value is the unicode "space" character (U+0020).

I can't think of a case but, hypothetically, if one's life actually depended on what padding was output, it may not be so good that JS automatically drops the digit 8, as in
'abc'.padStart(10, '12345678') // abc1234567
This seems to circumvent the intent of the programmer and seems to be just a shortcut for the convenience of JS. It might be better to throw an error like "RangeError" so the programmer can try to think of a better solution, imho.
Similarly for the last example when JS just "willy nilly" decides to not add padding instead of throwing an error.
