Learn the best practices for working with JavaScript objects, functions, and arrays to write more efficient, reusable, and maintainable code. This comprehensive guide covers everything you need to know, from naming conventions to performance optimization.
To make code easy to read and maintain, we should follow some best practices.
In this article, we’ll look at some best practices we should follow to make everyone’s lives easier.
We should have getter and setter pairs in our objects.
Without getters, properties can’t be read, so it’s not used.
For instance, instead of writing:
const obj = {
set a(value) {
this.val = value;
}
};
We write:
const obj = {
set a(value) {
this.val = value;
},
get a() {
return this.val;
}
};
We may put line breaks before the opening and closing brackets.
It’s clearer to have them for long arrays
For instance, instead of writing:
const arr= [1, 2, 3, 4, 5];
We write:
const arr = [
1, 2, 3, 4, 5
];
