Skip array function arguments in a JavaScript function like forEach, map, filter etc

Comment

// The "underscore" ( _ ) symbol will always be used for function arguments skipped. Check example below:
 
function(_, __, ___, ___, ____, fValue);
// or
function(_, _, _, _, _, fValue);

// example:

const arr = [ 1, 2, 3, 4, 5, 6, 7 ];

arr.forEach( value, index, array );

// What it should look like if I skip "VALUE" arguments:

arr.forEach( _, index, array )

// What it should look like if I skip "VALUE" arguments:

arr.forEach( value, __, array )

// What it should look like if I skip "VALUE and INDEX" arguments:

arr.forEach( _, __, array );

// and what if I skip "INDEX and ARRAY" arguments:

arr.forEach( value );
