You can edit your function in following way:

function getPokemonByName(name) {

const pokemonIndex = pokemon.findIndex((item) => item.name === name )

if (pokemonIndex > -1) return pokemon[pokemonIndex]

return 'Not Found'
}


Then you can call it using pokemon name.

getPokemonByName('Ivysaur')


This will give proper result.

You can still use your function by adding if statement with a for loop on the next_evolution and pre_evolution like this:

if

for loop

var pokemon = [{
"id": 1,
"num": "001",
"name": "Bulbasaur",
"img": "http://www.serebii.net/pokemongo/pokemon/001.png",

"Grass",
"Poison"
],
"height": "0.71 m",
"weight": "6.9 kg",
"candy": "Bulbasaur Candy",
"candy_count": 25,
"egg": "2 km",
"spawn_chance": 0.69,
"avg_spawns": 69,
"spawn_time": "20:00",
"multipliers": [1.58],
"weaknesses": [
"Fire",
"Ice",
"Flying",
"Psychic"
],
"next_evolution": [{
"num": "002",
"name": "Ivysaur"
}, {
"num": "003",
"name": "Venusaur"
}]
}, {
"id": 2,
"num": "002",
"name": "Ivysaur",
"img": "http://www.serebii.net/pokemongo/pokemon/002.png",
"type": [
"Grass",
"Poison"
],
"height": "0.99 m",
"weight": "13.0 kg",
"candy": "Bulbasaur Candy",
"candy_count": 100,
"egg": "Not in Eggs",
"spawn_chance": 0.042,
"avg_spawns": 4.2,
"spawn_time": "07:00",

],

"prev_evolution": [{
"num": "001",
"name": "Bulbasaur"
}],
"next_evolution": [{
"num": "003",
"name": "Venusaur"
}]
}]

function pokemonDetails(name) {
for (var i = 0; i < pokemon.length; i++) {
if (name == pokemon[i].name) {
y = pokemon[i]
for (var x in y) {
if(x === 'next_evolution') {
for (var z = 0; z < y[x].length; z++) {
console.log(x + " = " + "num: " + y[x][z].num + ", name: " + y[x][z].name + "n")
}
}else if (x === 'prev_evolution') {
for (var z = 0; z < y[x].length; z++) {
console.log(x + " = " + "num: " + y[x][z].num + ", name: " + y[x][z].name + "n")
}
} else {
console.log(x + " = " + y[x] + "n")
}

}
}
}
}


pokemonDetails('Ivysaur');
