I have an array that contains a set of objects And in these objects I want to change the value of a property :

var array=[{a:1, b:false}, {a:2, b:true}, {a:3, b:false}]

I want the propriety b to be true everywhere

var array=[{a:1, b:true}, {a:2, b:true}, {a:3, b:true}]

How do I do this?

Just use a loop with map:

const newArr = array.map((item) => ({ ...item, b: true }));

you can use two possible approaches:

yourArray.forEach(item=>item.b = true);

const updatedArray = temp.map(item=>{...item, b:true});

There are 2 ways you can achieve the result:

var array=[{a:1, b:false}, {a:2, b:true}, {a:3, b:false}]
array.forEach((obj) => {
   return obj.b = true
})

console.log(array)

var array=[{a:1, b:false}, {a:2, b:true}, {a:3, b:false}];

const result = array.map((item) => ({ ...item, b: true }));

console.log(result);
