How to usethe `slice()` method in Javascript
To get all substrings of a string using the `slice()` method, iterate over the string and slice it at every possible start and end index. Add each substring to a list. This method efficiently generates all substrings.
Example
function getAllSubstrings(str) {
const substrings = [];
for (let i = 0; i < str.length; i++) {
for (let j = i + 1; j <= str.length; j++) {
substrings.push(str.slice(i, j));
}
}
return substrings;
}
// Example usage:
const string = "abcd";
console.log(getAllSubstrings(string)); // Output: ["a", "ab", "abc", "abcd", "b", "bc", "bcd", "c", "cd", "d"]
Output
[ 'a', 'ab', 'abc', 'abcd', 'b', 'bc', 'bcd', 'c', 'cd', 'd' ]
How to Get All Substrings of the Given String in JavaScript ?
In this article, we are going to learn about getting all substrings of the given string by using javascript, Substrings of a string are contiguous sequences of characters obtained by selecting a range of characters from the original string. They can be of various lengths and positions within the string.
Example:
Input : abc
Output : [ 'a', 'ab', 'abc', 'b', 'bc', 'c' ]
There are several methods that can be used to get all substrings of the given string in JavaScript, which are listed below:
- Using recursive
- Using Array.reduce() and Array.concat()
- Using Nested Loops
We will explore all the above methods along with their basic implementation with the help of examples.
