How to reset all checkboxes using jQuery or pure JS?

If you mean how to remove the 'checked' state from all checkboxes:

$('input:checkbox').removeAttr('checked');

Javascript

var clist = document.getElementsByTagName("input");
for (var i = 0; i < clist.length; ++i) { clist[i].checked = false; }

jQuery

$('input:checkbox').each(function() { this.checked = false; });

To do opposite, see: Select All Checkboxes By ID/Class

Easy. by class GIVE ME A LIKE

$('.YUCLASS').prop('checked', false);

or

$('.YUCLASS').removeAttr('checked');

Resetall checkbox

<input type="checkbox" id="bike" name="vehicle" value="bike">
<label for="bike">Bike</label>
<input type="checkbox" id="car" name="vehicle" value="car">
<label for="car">Car</label>
<button id="select">Select All</button>

JavaScript #1

Get all the checkboxes using the name field,

document.getElementById('select').onclick = function() {
    var checkboxes = document.getElementsByName('vehicle');
    for (var checkbox of checkboxes) {
    checkbox.checked = false;
    }
}

JavaScript #2

If there is no other input tags other than checkboxes,

document.getElementById('select').onclick = function() {
    var checkboxes = document.getElementsByTagName("input");
    for (var checkbox of checkboxes) {
    checkbox.checked = false;
    }
}
