const splitSkip = require('split-skip');
//@param {String} str - Input String
const str = 'Some,String,as,an,Input';
// @param {String} separator - Specifies the character(s) to use for separating the string
const separator = ',';

const skipState = (state, char, i) => {
/*
Some logic to define state.skip equals to some truthy value
e.g. state.skip = true, state.skip = 1
when it should skip if the current char matches the separator
*/
/*
And define state.skip equals to some falsy value
e.g. state.skip = false, state.skip = 0
when it should get back splitting if the current char matches the separator
*/

As an input we have a string representing the parameters definition of a function from where we want to get each individual parameter. One idea of doing this is to split on every comma, but skipping the commas that are present on destructuring parameters definitions.
Using splitSkip, it could be like:
`javascript[destru,cturu,cing]=[1],param,{dd,ee,ff}={dd:{b:1,c:2,arr:[1,6]}},last
const input = ;
const result = splitSkip(input, ',', (state, char, i) => {
if ('{[('.indexOf(char) >= 0) {
state.skip += 1;
}
if ('}])'.indexOf(char) >= 0) {
state.skip -= 1;
}
return state;
});
// result === ['[destru,cturu,cing]=[1]', 'param', '{dd,ee,ff}={dd:{b:1,c:2,arr:[1,6]}}', 'last'];
