Requires Node.js version >= 14.
`js
const snakecase = require('snakecase');
// or
const { snakecase } = require('snakecase');
console.log(snakecase('a')); //=> 'a'
console.log(snakecase('foo bar baz')); //=> 'foo_bar_baz'
console.log(snakecase(' foo bar baz ')); //=> 'foo_bar_baz'
console.log(snakecase('foo_bar-baz')); //=> 'foo_bar_baz'
console.log(snakecase('foo.bar.baz')); //=> 'foo_bar_baz'
console.log(snakecase('foo/bar/baz')); //=> 'foo_bar_baz'
console.log(snakecase('foobar)baz')); //=> 'foo_bar_baz'
console.log(snakecase('#foo+bar*baz')); //=> 'foo_bar_baz'
console.log(snakecase('$foo~barbaz')); //=> 'foo_bar_baz'
console.log(snakecase('_foo_bar-baz-')); //=> 'foo_bar_baz'
console.log(snakecase('foo 2 bar 5 baz')); //=> 'foo_2_bar_5_baz'
console.log(snakecase('foo2bar5baz')); //=> 'foo2bar5baz'

Type: boolean
Default: false
This library attemps to sensibly match sequences of uppercase characters in a way that mirrors real-world usage. For example, the following is default behavior:
`js`
console.log(snakecase('JSONStringify')); //=> 'json_stringify
console.log(snakecase('TheIRSIsMean')); //=> 'the_irs_is_mean
However, if you wish to preserve upper case character sequences, you may pass an options object with the preserveConsecutiveUppercase option set to true:
`js`
console.log(snakecase('JSONStringify', { preserveConsecutiveUppercase: true })); //=> jsons_tringify
console.log(snakecase('TheIRSIsMean', { preserveConsecutiveUppercase: true })); //=> the_irsi_s_mean
Type: boolean
Default: false
Convert the output string to upper case.
`js`
console.log(snakecase('fooBarBaz', { uppercase: true })); //=> 'FOO_BAR_BAZ'
console.log(snakecase('FooBarBaz', { uppercase: true })); //=> 'FOO_BAR_BAZ'
All options are passed to [sindresorhus/camelcase, please visit that project to learn about all available options.
