var text_2=["a","b","c","d","e","f"];
var newarr=[];
for(var i=0;i<text_2.length;iPP){
newarr.push({i:text_2[i]});
}
console.log(newarr); Why is the object key from push I: "a"?
instead of 123456
var text_2=['a','b','c','d','e','f'];
var newarr=[];
for(var i=0;i<text_2.length;iPP){
newarr.push({[i]:text_2[i]});
}
console.log(newarr);
if you write I on key, he will default to the key name I, not the variable I
to {[I]: I}
Why use [] to frame I? Because [the name of the attribute] and the use. The name of the setting property is the same. It's just that the specific scene used is different, so the way to write it is different
look at the code:
var text_2=['a','b','c','d','e','f'];
var newarr=[];
for(var i=0;i<text_2.length;iPP){
// text_2[i] => a,b,c...
// i => 0,1,2,3,4...
newarr.push({[i]: text_2[i]});
}
