What does the -> operator do in the .js code below?
_blm.mpU_onIdentified(function() {
console.log('find_program_result.js -> mpU_onIdentified');
_blm.mpU.people.set({
'findProgramsResultsHref': location.href
});

This isn't an operator - it's inside a string which is being logged. You can identify it by the quotes enclosing it:
console.log('find_program_result.js -> mpU_onIdentified');
// quotes --^------------------------------------------^

Below is the code I currently using which I need to round the end result to 2 decimals.Can someone help me figure out what I did wrong.
total = panjang*ht+hf;
document.getElementById("ototal").innerHTML =eval(total(toFixed(2)));

The variable total is a number, not a function.
You should use toFixed function like this
total.toFixed(2)

I am trying a very basic javascript map example
var map1 = {'myKey1':11, 'mykey2':22};
var t = map1['mykey1'];
alert(t);
But the alert always gives me 'undefined', it should give me '11'
please guide what i am doing wrong

You have a spelling mistake there mate, notice that in your map1 object there is no mykey1 key actually, there is a myKey1 key however, containing a capital K

$("td[id^='td0_']")
My question is how can I replace 0 in the example above with a variable myvar?

You should be able to use:
$("td[id^='td" + myvar + "_']")

Use the quotes appropriately.
$("td[id^='td" + myvar +"_']")
