JavaScript - Delete First Character of a String

To delete the first character of a string in JavaScript, you can use several methods. Here are some of the most common ones

Using slice()

The slice() method is frequently used to remove the first character by returning a new string from index 1 to the end.

Using substring()

Similar to slice(), substring() creates a new string starting from index 1, effectively removing the first character.
