由于比较两个变量而出错

let a = {name: 'Alice'};
let b = {name: 'Alice'};

if (a == b) {
    console.log('Objects are equal');
} else {
    console.log('Objects are not equal');
}

if (JSON.stringify(a) === JSON.stringify(b)) {
    console.log('Objects are equal');
} else {
    console.log('Objects are not equal');
}

let num = 10;
let str = '10';

if (num == str) {
    console.log('Numbers are equal');
} else {
    console.log('Numbers are not equal');
}

if (num === parseInt(str)) {
    console.log('Numbers are equal');
} else {
    console.log('Numbers are not equal');
}

let a = 0.1 + 0.2;
let b = 0.3;

if (a == b) {
    console.log('Floats are equal');
} else {
    console.log('Floats are not equal');
}

if (Math.abs(a - b) < Number.EPSILON) {
    console.log('Floats are equal');
} else {
    console.log('Floats are not equal');
}
