JavaScript function array parameter | Example code

  • by

Use apply() method to use the array as a parameter in the JavaScript function.

const args = ['p0', 'p1', 'p2'];
function_name.apply(this, args);

If the environment supports ECMAScript 6, you can use a spread argument instead. The spread operator can do many other useful things.
