Converting strings to snake case in JavaScript

Snake case is basically a style of writing strings by replacing the spaces with '_' and converting the first letter of each word to lowercase.

We are required to write a JavaScript function that takes in a string and converts it to snake case.

Example

The code for this will be −

const str = 'This is a simple sentence'; const toSnakeCase = (str = '') => {    const strArr = str.split(' ');    const snakeArr = strArr.reduce((acc, val) => {       return acc.concat(val.toLowerCase());    }, []);    return snakeArr.join('_'); }; console.log(toSnakeCase(str));

Output

Following is the output on console −

this_is_a_simple_sentence
