[Javascript] Case insensitive sorting for string arrays

2024-08-31 19:16:16

We look at the default Array.prototype.sort behavior and discuss how you can do case insensitive string sorting.

const foo = [

  'Alpha',

  'beta',

  'Gamma',

  'delta'

];

foo.sort((a, b) => a.toLowerCase().localeCompare(b.toLowerCase()));

foo.forEach(x => console.log(x));

/*

"Alpha"

"beta"

"delta"

"Gamma"

*/
