`String.prototype.slice()`

Extracts a section of a string and returns it as a new string.

Syntax

str.slice(start, end)

Name	Type	Required	Description
`start`	`number`	No	Index where extraction begins. Negative counts from the end. Defaults to 0.
`end`	`number`	No	Index before which to end extraction (exclusive). Negative counts from the end. Defaults to string length.

string — A new string containing the extracted section.

console.log('hello world'.slice(0, 5));

Output

hello

console.log('hello'.slice(-3));

Output

llo

Supports negative indices (unlike `substring`). Strings are immutable, so this returns a new string and never mutates the original.
