Changing the case of a string using JavaScript

JavascriptWeb DevelopmentFront End TechnologyObject Oriented Programming

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

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

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

The output in the console will be −

this_is_a_simple_sentence
