Overview of VueJS 2 The Complete Guide by Max on Udemy

Section 2 - Using VueJS to Interact with the DOM

Section 3 - Using Conditionals and Rendering Lists

  • Use directive v-if for conditional rendering
  • v-if detach element from the DOM entirely, not just hide it. You can see inspecting the element.
  • You can use the v-else right after the v-if in order to show the opposite, but it must have to be next to the v-if in order to work.
  • Use <template> instead a <div> tag to group multiple elements and make them show or hide, prevent side effect to layout.
  • Use v-show to show/hide elements but not remove it from the DOM. The effect visually is the same as v-if but the element get a display: none/block ratherthan detach from DOM.
  • Use v-for for loop through a list (array/objects)
  • You can add a second parameter for v-for to get the index of element, like this: v-for="(ingredient, i) in ingredients". The name of parameters in parentesis is up to you, the only thing to remember is: first paramenter is the element itself, the second parameter is the index.
  • You can elaso use <template> with v-for loop to omit a wrapper tag.
  • Use v-for="n in 10" to loop through numbers. The number 10 in this case in the range.
