In TypeScript, for loop can be used to iterate a block of code for a specific range. The for loop has three important statements - initialization, condition and increment section.
Here's how you can use for loop with a step in TypeScript:
for (let i = 0; i < 10; i += 2) {
console.log(i);
}
// Output: 0 2 4 6 8
In the above example, let i=0 initializes the loop control variable to 0, i < 10 is the condition that checks whether the loop should continue or not, and i += 2 increments i by 2. The loop will run for as long as i < 10 condition is met, and the value of i is increased by 2 after each iteration.
You can also use variables or expressions that calculates the step size dynamically, for example:
const n = 10;
const step = 2;
for (let i = 0; i < n; i += step) {
console.log(i);
}
// Output: 0 2 4 6 8
In this example, the loop runs for 5 iterations, starting at 0 and incrementing by 2, until it reaches 8.
Hope this helps!
