to load underscore (or any cdn) into javascript:
var cdn = ‘https://code.jquery.com/jquery-3.2.1.min.js’ ;
var cdn = “https://cdnjs.cloudflare.com/ajax/libs/underscore.js/1.8.3/underscore-min.js” ;
var cdn=‘https://cdnjs.cloudflare.com/ajax/libs/deepstream.io-client-js/2.1.2/deepstream.js’ ;
var jq = document.createElement(‘script’); jq.src=cdn;
document.getElementsByTagName(‘head’)0.appendChild(jq);
awesome way to use underscore to look up value in an object:
// _master is the object, sequelizeId is the index
console.log( _.findIndex(_master, (_tmpRow)=> { return _tmpRow.sequelizeId === ‘123456’ }) );

var master = [ { ‘name’ : ‘listOne’ , data : [ ‘nameOne’,‘nameTwo’] } , { name: ‘listTwo’, ‘data’ : [ ‘nameThree’, ‘nameFour’ ] } ]
function findMe(myObj, myKey) {
var retVal=null;
_.each(myObj, (val)=> {
var byeBye = _.indexOf(val.data, myKey );
if ( _.indexOf(val.data, myKey ) > -1 ) {
retVal=val.name;
}
})
return retVal;
}
console.log( ‘RESULT: ‘ + findMe(master, ‘nameTwo’) )
