This article will explain in detail how javascript removes the first character of the string. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

In javascript, you can use the slice () method of the String object to remove the first character of a string with the syntax "string object .slice (1)"; the slice () method extracts the substring from the specified position to the end of the specified position in the string and returns the extracted part with a new string.

In javascript, you can use the slice () method of the String object to remove the first character of a string.

Example:

Const text = 'abcdef'const editedText = text.slice (1) console.log (editedText)

Description:

The slice () method extracts a portion of a string and returns the extracted part as a new string.

Syntax:

The string.slice (start,end) parameter describes that the start must. The starting subscript of the fragment to be extracted, with the first character position 0. If it is negative, it is intercepted from the tail. End is optional. Followed by the subscript at the end of the clip to be intercepted. If this parameter is not specified, the substring to be extracted includes the string from start to the end of the original string. If the parameter is negative, it specifies the position from the end of the string. Slice (- 2) means to extract the penultimate element from the original array to the last element (including the last element).

The position of the first character in the start parameter string is 0, the position of the second character is 1, and so on. If it is a negative number to indicate how many strings are intercepted from the tail, slice (- 2) means to extract the penultimate element from the original array to the last element (including the last element).

If the end parameter is negative,-1 refers to the position of the last character of the string,-2 refers to the penultimate character, and so on.

Return value: the extracted string.
