Script Preparation code:

function makeNode() {
  return {
    valid: Math.random() > 0.5
  };
}

function isNodeValid( node ) {
  return node.valid;
}

function isValid() {
  return this.valid;
}

const nodes = [];
for( let i = 0; i < 10000; i++ ) {
  const node = makeNode();
  node.isValid = isValid.bind( node );
  nodes.push( node );
}

function getNodes() {
  return nodes;
}

Tests:

Function
getNodes().forEach( node => isNodeValid( node ) );
Function bind
getNodes().forEach( node => node.isValid() );
Function bind and call
getNodes().forEach( node => isValid.bind( node )() );
Function call
getNodes().forEach( node => isValid.call( node ) );
