• Handling data using map() and filter() methods:
const instructions = [
{ id: 131 },
{ id: 132 },
{ id: 133 },
];
const instruction_ids = [
{ id: 169, instruction_id: 131 },
];
// Extract the instruction_id values from instruction_ids
const idsToRemove = instruction_ids.map(item => item.instruction_id);
// Use the filter method to remove objects with matching instruction_id values
const updatedInstructions = instructions.filter(item => !idsToRemove.includes(item.id));
console.log(updatedInstructions);
• Handling data using Set() and filter() methods.
const instructions = [
{ id: 131 },
{ id: 132 },
{ id: 133 },
];
const instruction_ids = [
{ id: 169, instruction_id: 131 },
];
// Create a Set of idsToRemove for efficient lookup
const idsToRemoveSet = new Set(instruction_ids.map(item => item.instruction_id));
// Use the filter method with the Set for faster lookups
const updatedInstructions = instructions.filter(item => !idsToRemoveSet.has(item.id));
console.log(updatedInstructions);
• Handling data using Set() and reduce() methods.
const instructions = [
{ id: 131 },
{ id: 132 },
{ id: 133 },
];
const instruction_ids = [
{ id: 169, instruction_id: 131 },
];
// Create an object for efficient lookup
const idsToRemoveMap = instruction_ids.reduce((map, item) => {
map[item.instruction_id] = true;
return map;
}, {});
// Use the filter method to remove objects with matching instruction_id values
const updatedInstructions = instructions.filter(item => !idsToRemoveMap[item.id]);
console.log(updatedInstructions);
• Use for-loop to handle:
const instructions = [
{ id: 131 },
{ id: 132 },
{ id: 133 },
];
const instruction_ids = [
{ id: 169, instruction_id: 131 },
];
const updatedInstructions = [];
for (const instruction of instructions) {
let shouldInclude = true;
for (const idItem of instruction_ids) {
if (instruction.id === idItem.instruction_id) {
shouldInclude = false;
break;
}
}
if (shouldInclude) {
updatedInstructions.push(instruction);
}
}
console.log(updatedInstructions);
