Why doesn't the if statement work?

• 0
  Good evening. There are selects and they must change some values ​​depending on the option selected at the moment, but for some reason the construction through if fulfills only 1 condition and that's all, but through the switch everything works as it should.
  

  if(e.target.value = 'amd') {
      ads.textContent = amd
   } else if(e.target.value = 'azn') {
       ads.textContent = azn
    } else {
       ads.textContent = usd
    }

  
  where is the mistake? Should work the same as with
  

  switch(e.target.value) {
     case 'amd':
        ads.textContent = amd
        break;
     case 'azn':
        ads.textContent = azn
        break;
      case 'usd':
        ads.textContent = usd
        break;
   }

  if(e.target.value === 'amd') { // '=' => '==='
  
      ads.textContent = amd
  
  } else if(e.target.value === 'azn') { // '=' => '==='
  
       ads.textContent = azn
  
  } else {
  
       ads.textContent = usd
  
  }

  No, it will work differently. else will intercept everything except amd, azn.
  
  Switch will only work on 3 variants.

  if (e.target.value = 'amd')
  
  In ifs, you have a spelling mistake, instead of a comparison, you make an assignment. Instead of one "=" sign, there should be "=="
