1. Problems
1. I always thought that the key value of an object cannot be declared with a variable. Writing this way the compiler will report an error:
obj = {
item.key[0]: [e[0]],
item.key[1]: [e[1]]
};Two, the solution
1. Today, I saw the code written by the boss and suddenly found that it can be done, just put the variable in the square brackets !
obj = {
[item.key[0]]: [e[0]],
[item.key[1]]: [e[1]]
};3. Summary
1. It's amazing, it seems that people really need to keep learning to surpass themselves! ! ! ! ! !
2. obj={[varKey]:value}
