How do I convert a string array:
var names = [
"Bob",
"Michael",
"Lanny"
];
into an object like this?
var names = [
{name:"Bob"},
{name:"Michael"},
{name:"Lanny"}
];

Super simple Array.prototype.map() job
names.map(name => ({ name }))
That is... map each entry (name) to an object with key "name" and value name.
var names = [
"Bob",
"Michael",
"Lanny"
];
console.info(names.map(name => ({ name })))Silly me, I forgot the most important part
names.map(name => name === 'Bob' ? 'Saab' : name)
.map(name => ({ name }))

Haha thanks, Phil :) That "Saab" was a spelling mistake, but I loved that you related to it and gave an answer to that too.
Use the Array.map() function to map the array to objects. The map() function will iterate through the array and return a new array holding the result of executing the function on each element in the original array. Eg:
names = names.map(function(ele){return {"name":ele}});

You can do this too:
var names = [
"Bob",
"Michael",
"Lanny"
];
var objNames = []
names.forEach(name => {
objNames.push({
name
})
})
Using ES6 you can set name and it is equal to name: name

you can use the map function. In general, list.map(f) will produce a new list where each element at position i is the result of applying f to the element at the same position in the original list. For example:
names.map(function(s) {
return {name: s}
});
names[i] = {name: names[i]}.
